Secure Fixings for Concrete, Masonry & Trade Installations

What are you fixing & what are you fixing it into?

Those two details should come before anchor diameter.

Hobson | Anchors provide professional fastening options for construction, fabrication, workshop, plant & maintenance applications. Across concrete, masonry & other suitable substrates, the right anchor depends on how the fixing needs to work as part of the complete connection.

Fixture thickness, base material, fixing position, embedment, spacing, edge distance, material finish & installation method all deserve consideration before the first hole is drilled.

► Match the anchor to the substrate & application
► Secure brackets, base plates, frames & equipment
► Account for fixture thickness before selecting length
► Plan fixing positions, spacing & available depth
► Select material & finish for the working environment
► Follow the installation requirements for the exact anchor

What Are Hobson Anchors?

Hobson anchors are fastening products designed to secure fixtures, components & equipment into suitable base materials.

The important difference between anchor types is how the fixing engages with the substrate.

Mechanical anchors create their connection through physical engagement with the base material. Depending on the anchor, this can involve threading, expansion, wedging or another mechanical action.

Chemical anchoring takes a different approach. A compatible anchor element is installed with a suitable resin into a correctly prepared hole, creating a bonded fixing after the required curing period.

That means an anchor should never be selected on diameter alone.

Before choosing, establish:

► Base material
► Fixture type & thickness
► Required fixing method
► Anchor dimensions
► Available embedment
► Fixing position
► Edge distance & spacing
► Environmental exposure
► Installation requirements

Why Choose Hobson Anchors?

Because the fixing needs to suit more than the hole.

Concrete, brick, block & other building materials can present very different anchoring conditions. The fixture itself can also change what is required from the connection.

The objective isn't to find the biggest anchor that fits.

It's to select a fixing that suits the substrate, fixture & conditions as a complete installation.

Common Applications

Base Plates, Steel Frames & Brackets

Fabricated brackets, frames, plates & supports often arrive with predetermined fixing positions.

Before drilling, check that those positions provide suitable spacing, edge clearance & available installation depth for the selected anchor.

Machinery & Equipment Hold-Down

Machinery, workshop equipment, guards & fabricated supports may introduce vibration, movement or repeated operational loads.

Don't consider static weight in isolation. The complete connection needs to suit how the equipment will operate once installed.

Concrete Fixing

Concrete anchors are used across construction, civil, workshop & maintenance environments for attaching fixtures to suitable concrete substrates.

Concrete condition, fixing location, anchor type, drilling requirements & fixture thickness should be checked before installation begins.

Brick & Masonry Fixing

Brick & block aren't simply concrete with a different appearance.

The construction type, condition of the substrate & fixing location can change which anchoring method is appropriate.

Confirm compatibility with the actual base material rather than assuming every concrete anchor can also be installed into masonry.

Retrofit & Maintenance Work

Existing structures can make anchor selection less straightforward.

Old fixing holes, concealed base materials, deteriorated areas, nearby edges & restricted drilling access may affect where a new fixing can be positioned.

Inspect first. Drill second.

Product Selection Guide – Choose the Anchor From the Job Backwards

Identify the Substrate

Start with the material receiving the fixing.

Is it:

► Solid concrete
► Brick
► Masonry
► Block
► Another specified substrate

Surface appearance alone isn't always enough, particularly during renovation & maintenance work.

Check the Fixture

What are you actually attaching?

Measure the fixture thickness & check the fixing-hole positions before choosing anchor length.

Understand the Connection

A light bracket, structural component & machinery base aren't equivalent installations.

Consider the demands the connection will face in service.

Check the Fixing Position

Look at available substrate depth, nearby edges, adjacent anchors & existing holes.

Don't move the fixing point simply because another position is easier to drill.

Consider the Environment

Indoor dry conditions can require different material considerations from exposed, wet or more aggressive environments.

Choose the anchor material & finish around the intended service conditions.

Confirm the Installation Requirements

Check the drill diameter, hole depth, embedment, tightening method & any preparation requirements applicable to the exact anchor.

Mechanical or Chemical Anchoring?

Neither is automatically the better choice.

They solve fixing requirements differently.

Mechanical Anchors

Mechanical anchors create a physical connection with the substrate. Different designs can use expansion, wedging, threading or other mechanical engagement.

They can provide an efficient fixing method where the selected anchor is suitable for the substrate, connection & installation conditions.

Chemical Anchoring

Chemical anchor studs are non-expansion fasteners installed into pre-drilled holes using a compatible curing resin.

This type of fixing can suit concrete or masonry anchoring & machinery hold-down applications where the selected system is appropriate. Installation requires correct hole preparation, resin application & sufficient curing time before loading.

The choice between mechanical & chemical anchoring should therefore start with the connection requirements, not installer habit.

What We Check When Selecting Anchors?

When you're comparing anchors for a job, a few pieces of information quickly narrow the options.

What Is the Substrate?

Concrete? Brick? Block? Masonry?

Start here. A fixing has to suit the material receiving it.

What Is Being Attached?

Know the fixture dimensions & thickness.

This prevents selecting an anchor that appears long enough until the fixture itself is taken into account.

Where Will the Fixing Sit?

Check nearby edges, other fixing points, existing holes & available depth.

Position matters just as much as anchor size.

How Will the Connection Work?

Consider whether the completed installation will experience movement, vibration or other operational demands.

Where Will It Spend Its Working Life?

Environmental exposure can influence the material & finish required.

Bringing these details together before ordering gives you a much better starting point than simply asking for an M10, M12 or M16 anchor.

Get the Hole Right Before the Anchor Goes In

Even the correct anchor needs the correct installation.

Before drilling:

► Confirm the fixing position
► Identify the actual substrate
► Measure the fixture
► Check the required drill diameter
► Confirm drilling depth
► Account for edges & adjacent anchors
► Prepare the hole as required
► Use the specified installation procedure

An incorrectly drilled hole shouldn't be “fixed” by substituting whatever anchor happens to fit.

Likewise, don't assume the drill used for one anchor is correct for another because both fixings share the same nominal diameter.

Expert Tips – Small Decisions That Matter

Measure Fixture Thickness Before Ordering

Anchor length needs to account for both the fixture & the required installation into the substrate.

Measure rather than estimate.

Don't Oversize the Hole

More clearance isn't automatically helpful.

Use the hole dimensions required for the particular anchoring system.

Treat Edge Fixings Differently

A fixing near an edge doesn't have the same amount of surrounding substrate as one positioned well inside the material.

Check the requirements of the selected anchor before committing to the hole.

Don't Assume the Substrate

Renovation & maintenance work can hide different base materials behind similar-looking finishes.

Confirm what you're drilling into.

Keep Different Anchors Separated on Site

Where several anchoring systems are being used, keep products clearly identified.

A similar diameter doesn't make two anchors interchangeable.

Follow the Product-Specific Installation Method

Mechanical screw anchors, expansion anchors & chemical anchoring systems work differently.

Use the installation procedure for the actual product rather than applying one familiar method to everything.
