Reusable Threaded Fastening for Fabrication & Repairs

Need a secure threaded fixing where you cannot reach the back of the panel? Geiger Nutserts & rivet nuts create reusable female threads in correctly prepared materials, giving mechanics, fabricators & maintenance teams a practical fastening solution for one-sided access.

The current Geiger range covers steel Poly Nut threaded inserts from M4 to M12, with M4, M5, M6, M8, M10 & M12 options available for different metric fastening requirements. These inserts suit applications where a conventional loose nut is impractical & a removable bolted connection is preferred over permanent blind riveting.

Although this collection sits within Industrial Shed's Rivet & Nutsert Kits category structure, the current Geiger products are individual Nutsert packs rather than complete installation kits. For riveters, nut riveter sets & complementary fastening tools, explore Clips & Rivets.

Which Geiger Nutsert Size Do You Need?

Choosing a threaded insert starts with the bolt thread required by the assembly—not simply the largest Nutsert that fits the panel.

► M4 Nutsert – compact metric threaded fixing for appropriately designed smaller assemblies
► M5 Nutsert – another smaller-format option for compatible M5 fastening requirements
► M6 Nutsert – useful where the assembly is designed around an M6 machine thread
► M8 Nutsert – steps the fastening system up to an M8 internal thread
► M10 Nutsert – provides a larger metric thread for compatible assemblies
► M12 Nutsert – the largest thread size currently available in this Geiger collection

Thread size alone does not determine suitability. Installation-hole diameter, parent material, material thickness, grip requirements, installation tooling & expected service conditions must also match the exact insert being used.

Accurate hole preparation is part of that system. Drill Bit Sets provide workshop options for preparing holes in suitable materials before the threaded insert is installed.

What Are Nutserts & Rivet Nuts?

A Nutsert, commonly called a rivet nut, rivnut or threaded insert, is a fastener designed to create a captive female thread in a prepared hole.

Unlike a conventional nut-and-bolt arrangement, installation can be performed from the accessible face when the chosen product & application permit blind installation. The insert is set into the workpiece using compatible installation tooling, creating a threaded fixing point for the corresponding bolt or machine screw.

That makes rivet nuts particularly useful in fabricated panels, enclosed sections, equipment housings & other assemblies where holding a loose nut behind the workpiece would be difficult or impossible.

The resulting threaded connection also allows a compatible fastener to be removed later, making Nutserts valuable where covers, brackets or components require future servicing.

Why Choose Nutserts for Thin Material & One-Sided Access?

Thin sheet creates a fastening problem that conventional tapping cannot always solve effectively.

When the parent material does not provide sufficient thickness for the required thread engagement, a correctly selected threaded insert can introduce a dedicated female thread rather than relying on threads cut directly into the sheet.

Rear access is another major consideration. Closed sections, vehicle panels, fabricated housings & assembled equipment may leave no practical way to hold a conventional nut behind the workpiece.

A Nutsert can solve that access problem while preserving a removable threaded connection.

That combination—blind-side installation potential + reusable machine thread—is what separates rivet nuts from many other workshop fasteners.

Where a job extends beyond threaded inserts into general bolts, rivets & fastening hardware, Bolt Bar – Fasteners, Rods & Anchors provides complementary fastening options for fabrication & repair work.

Common Applications for Geiger Rivet Nuts

Automotive Fabrication & Accessory Mounting

Vehicle panels, brackets & enclosed sections often leave little or no access behind the fixing point.

A correctly specified Nutsert can provide a captive thread for suitable removable brackets, guards, covers & fabricated accessories without requiring a loose nut behind the panel.

Sheet-Metal Fabrication

Sheet-metal assemblies frequently need threaded fixing points despite having limited material thickness.

Rather than relying on a shallow tapped thread, fabricators can use an appropriate rivet nut to introduce a dedicated threaded insert into the prepared hole.

Machinery Guards & Service Panels

Maintenance access changes the fastening requirement.

Guards, covers & panels that need periodic removal can benefit from reusable threaded fixings, allowing technicians to unbolt the component for servicing & reinstall it afterwards.

Equipment Housings & Enclosures

Enclosed housings can make conventional nuts difficult to position or retain.

Where the material, insert specification & engineering requirements are suitable, blind-installed threaded inserts can provide accessible fixing points from the working face.

Repair & Retrofit Work

Adding a mounting point after equipment has already been assembled can be difficult when dismantling the complete structure is impractical.

Nutserts provide another option for appropriate retrofit work because the installation can be completed from one side of the workpiece.

Workshop & Production Fabrication

Repeat assembly demands consistency.

Once the correct insert, prepared hole & installation settings have been established, rivet nuts can form part of a repeatable fastening process across suitable fabricated components.

For wider vehicle repair & workshop requirements, Automotive & Mechanical connects threaded fastening with the broader tooling used across mechanical servicing & fabrication.

Nutsert vs Rivet vs Tapped Thread – Choose the Fastening Method Around the Job

Different fastening methods solve different problems, so treating them as interchangeable can lead to poor product selection.

Nutsert / Rivet Nut

Choose an appropriate Nutsert when the assembly requires a reusable female machine thread, particularly where access is available from only one side.

Blind Rivet

Choose a blind rivet when suitable materials need to be joined with a blind fastening method & a reusable internal machine thread is not required.

A conventional blind rivet normally needs to be drilled out if the joined component later needs to be separated.

Tapped Thread

Choose a tapped hole when the parent material, thread engagement & engineering requirements make direct internal threading appropriate.

Thin material may not always provide enough depth for the desired thread, which is one reason threaded inserts are useful in fabrication.

The correct choice depends on whether the assembly needs permanent joining, removable fastening, rear access, adequate parent-material thickness or a captive reusable thread.

How to Choose the Right Geiger Nutsert?

A successful installation depends on the complete fastening system rather than the thread designation alone.

Match the Internal Thread

Begin with the bolt or machine screw specified for the assembly.

An M6 fastener requires the corresponding M6 threaded insert. The same principle applies across the current Geiger M4, M5, M6, M8, M10 & M12 range.

Confirm the Correct Hole Diameter

Do not use the nominal thread size as the drill-size instruction.

The required installation hole is determined by the exact insert specification. Check the manufacturer's technical data before drilling, especially where fit & repeatability matter.

Check Parent-Material Thickness

The insert must suit the material thickness it is being installed into.

An incorrect grip relationship can affect how the Nutsert sets, so verify the product specification against the workpiece before starting a batch installation.

Consider Parent Material & Environment

Steel sheet, aluminium, plastics & other substrates do not behave identically.

Material compatibility, corrosion environment, joint design & service conditions should all be considered before selecting the insert.

Match the Installation Tooling

Nutsert installation tools use compatible mandrels & nosepieces to engage & set particular thread sizes.

Confirm that the tool setup matches the Geiger insert before installation rather than assuming a standard blind-rivet gun will perform the same task.

Plan for Serviceability

Think about what happens after installation.

If a cover, bracket or component will be removed repeatedly, the threaded insert, mating fastener & surrounding material should all be appropriate for that service cycle.

Trade workshops buying fastening consumables repeatedly can simplify procurement through Trade Account Support, with trade pricing, approved account terms & purchasing support for professional businesses.

Getting a Nutsert Installation Right

Preparation determines whether the insert has the conditions it needs to set correctly.

Start by confirming the exact manufacturer's installation specification. Drill the required hole accurately, remove burrs that could interfere with seating & inspect the surrounding material before inserting the fastener.

Next, fit the correct mandrel & nosepiece to the compatible installation tool. Thread the Nutsert onto the mandrel correctly & position the tool square to the workpiece.

During setting, keep the tool aligned rather than pulling it sideways. The insert needs to collapse or set according to its design so it clamps against the parent material.

After installation, inspect the flange seating & check that the insert remains secure when the mating fastener is installed. A Nutsert that rotates in the hole needs investigation rather than simply being ignored.

For fabrication teams comparing complete installation systems rather than inserts alone, the broader Clips & Rivets range includes nut riveter sets, rivet guns & other fastening tools.

Expert Tips for Reliable Rivet Nut Installation

Good results come from controlling the variables before the first production insert is set.

► Use the specified hole diameter. An oversized or poorly prepared hole can compromise installation.
► Deburr before setting. Raised edges can prevent the insert flange from seating correctly.
► Keep the tool square. Correct alignment supports a more consistent set.
► Match mandrel & thread size. Installation tooling must correspond with the insert being used.
► Avoid uncontrolled over-setting. Excessive setting force can damage the insert, thread or parent material.
► Test unfamiliar combinations first. Trial installation in representative scrap material can reveal setup problems before they reach the finished component
► Check for insert rotation. A fitted Nutsert should remain secure during appropriate fastener installation & removal.
► Protect prepared metal where required. Drilling can expose bare substrate, so consider suitable corrosion protection for the application.
