High-Performance Concrete Fixing Without Expansion Pressure

Working close to a concrete edge, fastening overhead services or installing a fixture that may eventually need to be removed can change the anchor choice completely. ICCONS® | Screw Bolts - Toge cover the TOGE TSM family of high-performance screw-bolts developed for demanding concrete fastening. Their self-tapping action creates a positive mechanical connection without conventional expansion pressure in most base materials, making the system particularly useful where concrete geometry, installation speed, high load performance or future removal influence the fixing decision.

Australian builders, concrete contractors, façade installers, mechanical trades & services crews can choose from applicable hex, countersunk, pan-head & hanger configurations, with zinc-clear & selected 316 stainless steel options available across the family. Current TOGE TSM configurations include approvals for cracked concrete, fire applications & seismic work where documented for the exact anchor. Prepare the wider installation through Concrete Cutting & Drilling Tools,  Measuring & Leveling Tools &  Safety & Personal Protective Equipment.

Key characteristics across applicable TOGE TSM configurations include:

► Self-tapping concrete screw-bolt construction
► High load performance in cracked & non-cracked concrete
► Undercut load transmission
► No conventional expansion pressure in most base materials
► Close-to-edge fixing characteristics
► Immediate loading after correct installation
► Removable anchor construction
► No residual metal anchor component left in the hole after removal
► Hex, countersunk & pan-head options
► Concrete hanger configurations
► Zinc-clear variants
► Selected 316 stainless steel variants
► NCC-compliant configurations
► ETA-approved configurations
► Fire-rated configurations
► C1 seismic assessment across applicable configurations
► C2 seismic assessment for applicable carbon-steel configurations

The exact part number remains the authority for dimensions, embedment, material, assessment & installation limits.

Why Concrete Edges Put TOGE TSM on the Shortlist?

Anchor location becomes especially important when a base plate or bracket lands near the edge of a concrete element.

Conventional expansion anchors develop forces as their expansion mechanism activates. TOGE TSM takes a different approach, producing a positive screw connection that ICCONS describes as free of expansion pressure in most base materials.

That characteristic makes the range relevant to appropriately designed:

► Balustrade plates
► Handrails
► Guardrails
► Façade brackets
► Machinery bases
► Steel framing
► Window systems
► Protective barriers
► Service supports

A low-expansion installation characteristic does not make edge distance irrelevant. Concrete strength, anchor spacing, edge distance, embedment & design loads still need to satisfy the requirements of the selected fixing.

The Thread Creates the Working Connection

TOGE TSM does not need a separate sleeve to activate inside the drilled hole.

Its screw-bolt geometry forms the connection as the anchor is driven into correctly prepared concrete.

ICCONS describes the range as using undercut load transmission, supporting high load performance in cracked & non-cracked concrete.

This gives the installer a straightforward fixing sequence while avoiding a separate expansion component.

The practical benefits include:

► One-piece installation
► No loose expansion sleeve
► Immediate load capability after correct installation
► Removability
► Minimal residual material after removal

Simple installation should still be treated as a controlled installation.

The anchor only performs as intended when hole diameter, depth, alignment, cleaning, embedment & installation torque are correct.

A Fixture Can Tell You Which Head to Buy

Look at the component being anchored before deciding that every concrete screw should have the same head.

Hex Head

A socket-driven hex head suits many brackets, plates, steel frames, machinery bases & general construction connections where direct driver access is available.

Countersunk Head

A countersunk TOGE TSM suits appropriately prepared fixtures where the head needs to finish within the component rather than standing proud.

Pan Head

Pan-head configurations provide another interface for suitable thin fixtures & components requiring a broader, lower-profile head.

Hanger Connection

TOGE concrete hanger screws move away from a conventional fixture head entirely, providing a threaded connection for compatible suspended-service systems.

For socket, driver & associated installation requirements, Power Tool Accessories can be considered when preparing the job kit.

Hex-Head TSM Gives Buyers the Broadest Diameter Choice

Heavy brackets & structural fixtures often lead contractors towards the socket-driven side of the TOGE range.

Current ICCONS technical information documents hex-head TSM anchors across 6 mm, 8 mm, 10 mm, 12 mm & 14 mm diameters.

The dimensional relationship changes throughout the range.

Representative carbon-steel configurations include:

Notice that increasing overall anchor length does not always produce the same increase in fixture allowance.

Embedment requirements change too.

Order from the exact technical row rather than selecting purely from nominal diameter × length.

Seismic Work Needs the Exact Embedment, Not Just the Right Diameter

Two anchors of the same diameter can have different seismic status when their embedment changes.

Current ICCONS technical data specifies C1 seismic assessment for applicable carbon-steel & stainless-steel TSM configurations at defined embedment depths.

For carbon-steel C2 applications, the documented embedments include:

► TSM08 – 65 mm
► TSM10 – 85 mm
► TSM12 – 100 mm
► TSM14 – 115 mm

C2 assessment applies to the specified carbon-steel configurations.

That distinction matters when preparing seismic MEP bracing, cable supports, strut systems or other engineered connections.

Do not convert “TOGE is seismic approved” into a blanket approval for every size, material & embedment.

Overhead Services Create a Different Purchasing List

Installing a cable tray or fire-services support above head height is not just an anchor purchase.

The crew may need to coordinate:

► Concrete anchor
► Threaded connection
► Strut
► Pipe or conduit support
► Nuts & washers
► Drilling equipment
► Socket or driver
► Hole-cleaning equipment
► Access equipment
► Required site protection

TOGE TSM is documented as suitable for overhead applications, including compatible cable-tray, MEP, plumbing & fire-service installations.

For the fastening hardware used throughout the remaining support assembly, Nuts & Washers provides a useful adjoining collection.

Concrete Hanger Screws Remove an Extra Connection Step

Suspended pipework or ductwork can benefit from an anchor designed around threaded support from the beginning.

The TOGE TSM hanger family includes internal & external threaded configurations.

Current ICCONS documentation identifies 6 mm internal-thread hanger anchors with M8/M10 connections, alongside an external M8 hanger format within the wider system.

These can form part of suitable installations involving:

► HVAC ductwork
► Conduit
► Pipe support
► Fire protection services
► Cable tray
► Strut channel
► Ceiling suspension
► Other compatible threaded support systems

The hanger should be selected as part of the complete suspended system rather than treated as a generic concrete screw with a different top.

Cracked Concrete Changes the Fixing Requirement

A concrete anchor selected only for intact laboratory-style concrete may not suit the conditions assumed by an engineered connection.

Applicable TOGE TSM configurations carry cracked-concrete approval.

That capability makes the range relevant to appropriately designed structural & services connections where crack conditions form part of the assessment.

ICCONS identifies applications including:

► Structural fixings
► Tunnel fit-out
► Façade structures
► Seismic bracing
► Steel strut support
► Machinery & plant
► Guardrails
► Racking
► Steel-frame construction
► Timber-frame connections to concrete

Where cracked-concrete performance is required, retain the exact anchor designation through specification, purchasing & installation.

The Fastener Guide Bolts Screws Anchors provides broader guidance on distinguishing common fastening systems.

Stainless Steel Changes More Than Corrosion Resistance

Moving from zinc-clear carbon steel to 316 stainless steel can alter the installation dimensions attached to the anchor.

Selected TOGE TSM configurations are available in 316 stainless steel for installations where material selection calls for greater corrosion resistance.

However, the stainless version should not be treated as a material-only swap.

Depending on the configuration, changing material can affect:

► Available lengths
► Embedment depth
► Maximum fixture thickness
► Assessment status
► Installation parameters

Recheck the technical information whenever the material changes.

For external, façade or corrosion-sensitive work, the complete fixing environment should determine whether stainless steel is required.

A Worn Drill Bit Can Put the Hole Outside Specification

Concrete anchors are sensitive to the hole they are expected to engage.

ICCONS specifically instructs installers not to use a worn drill bit outside tolerance.

Before a large TOGE installation begins, check:

► Required drill diameter
► Condition of the bit
► Drilling depth
► Hole alignment
► Concrete condition
► Hole-cleaning equipment

For ongoing drilling work,  Drill Accessories provides a relevant route for bits & associated consumables.

The cost of replacing a worn bit is easier to manage than discovering a sequence of fixing holes has been prepared incorrectly.

Five Degrees Is the Maximum Drilling Deviation ICCONS Specifies

A hole that visibly wanders away from perpendicular deserves attention before an anchor is driven into it.

Current TOGE installation guidance requires the hole to be drilled perpendicular to the concrete, with a maximum deviation of 5 degrees.

Excessive angular deviation may contribute to anchor breakage.

For consistent installation:

► Establish the fixing centre
► Position the drill squarely
► Maintain alignment through the hole
► Reach the required depth
► Withdraw the bit under control
► Inspect the prepared hole

Accurate drilling becomes particularly important where several anchors must align through a rigid steel base plate.

Drill Deeper Than the Anchor Embedment

Required embedment & required drill depth are not the same measurement.

ICCONS instructs installers to drill the hole to the required anchor embedment depth plus at least one anchor diameter deeper.

That extra depth forms part of correct hole preparation.

For example, an anchor requiring a particular embedment should not be installed into a hole drilled only to that exact nominal depth.

Always use the drill-depth requirement applicable to the selected TSM configuration.

Clear the Hole Before the Thread Starts Cutting

Concrete dust occupying the drilled hole is material the anchor should not have to push out of its own way.

ICCONS requires dust & other material to be removed before installation.

A well-prepared fixing station can include:

► Correct masonry drill bit
► Suitable hammer drill
► Blow pump
► Hole brush where required
► Correct socket or Torx drive
► Torque wrench or suitable impact driver
► TSM anchors kept in identifiable packaging

Installation Torque Has a Hard Upper Limit

A bigger impact driver can become a liability when its output exceeds the fixing requirement.

TOGE TSM technical data includes maximum impact-tool torque values.

Representative hex-head limits include:

► 6 mm – up to 160 Nm for applicable configurations
► 8 mm – up to 300 Nm for applicable configurations
► 10 mm – up to 400 Nm for applicable configurations
► 12 mm – up to 650 Nm for applicable configurations
► 14 mm – up to 650 Nm for applicable configurations

These figures are not target tightening torques.

They are maximum impact-tool torque limits for the documented configurations.

Excessive torque can damage the anchor.

Engage the First Thread Before Driving the Anchor Home

Controlled starting helps the screw-bolt establish its intended path into the prepared hole.

ICCONS installation guidance calls for pressure against the fixing while rotating the anchor to engage the first thread.

From there, tighten until the anchor is firmly seated.

The sequence is straightforward:

► Prepare the correct hole
► Clean it
► Confirm fixture clearance
► Position the fixture
► Apply pressure to the fixing
► Rotate to engage the initial thread
► Drive the anchor
► Seat it firmly
► Avoid overtightening

Installation speed comes after control.

Temporary Equipment Fixing Has a Dedicated Gauge Procedure

Certain TOGE anchors can serve a specialised temporary role, but reuse is governed by more than visual inspection.

Selected 10 mm, 12 mm & 14 mm TSM screw-bolts are documented for temporary fastening of construction-site equipment when used strictly with the relevant TOGE tube/ring gauge system.

Available gauge sizes include:

► 10 mm
► 12 mm
► 14 mm

This temporary-use system must follow the applicable approval & gauge instructions.

A loose TSM anchor should never be assumed suitable for repeated use simply because it appears undamaged.

What the Tube/Ring Gauge Actually Changes?

The gauge introduces a controlled assessment step into temporary anchor use.

Where the approved temporary-equipment procedure applies, keep:

► 10 mm anchors with the 10 mm gauge
► 12 mm anchors with the 12 mm gauge
► 14 mm anchors with the 14 mm gauge

Mixing gauges, guessing from appearance or applying the procedure to an unlisted anchor removes the control that the system is designed to provide.

Crews using reusable construction fixings should keep the anchors, gauge & applicable instructions together.

TOGE TSM or a Conventional Expansion Anchor?

The right comparison is based on how the connection needs to behave, not which box is more familiar.

Both anchor types have legitimate applications.

The concrete, fixture, edge geometry, required assessment & installation method determine which system belongs in the connection.
