Metal Threaded Inserts for Brisbane

Clinch Nuts, Standoffs & Rivet Nuts

What We Offer

Samin Sheet Metal supplies metal threaded inserts to Brisbane and surrounding Queensland businesses, covering the full range of press-in and clinch-style fasteners used in precision sheet metal fabrication. This page adds detail on insert types, compatible materials, sheet thickness requirements, and how threaded inserts fit into the wider fabrication workflow.

Threaded Inserts

These commonly used fasteners can be inserted into thin sheet metal and are generally installed any time after a folding operation has been completed. They can also be installed into RHS material and other similar types of sections.

Clinch Nuts and Standoffs

Our Haeger brand of fastener-inserting machines are world leaders in inserting various types of standard clinch nuts and standoffs. Generally, this process takes place after the folding stage. In some cases, however, they can be installed during or before the folding processes, depending on the unique project circumstances.

Structural Rivets

Structural rivets are mainly used for special applications, particularly for designs that require a fastening system that is stronger than what standard rivets can provide.

What Are Threaded Inserts Used for in Sheet Metal?

Threaded inserts create permanent, load-bearing threaded connections in sheet metal panels too thin to hold a tapped thread reliably. They allow bolted assemblies to be disassembled and reassembled repeatedly without stripping parent material, making them a preferred fastening method in electronics enclosures, HVAC panels, machine guards, and structural brackets across Queensland.

Threaded Insert Types Explained

Several categories of metal threaded inserts may be specified depending on access, load requirements, and sheet thickness.


Clinch nuts (self-clinching nuts) press into a punched hole under squeezing force, displacing parent material into an annular groove to resist pull-out and rotation. Suited to steel and aluminium panels with sufficient ductility.


Rivet nuts (blind threaded inserts) are installed from one side only, expanding behind the sheet to create a threaded anchor where rear access is restricted. For more detail, visit our metal rivet inserts page.


Threaded standoffs provide a fixed separation between two panels while delivering a threaded connection. Common in PCB mounting, control panels, and enclosure assemblies.


Clinch studs press a male thread from the panel surface, enabling nut-and-bolt assembly without welding.

Compatible Materials and Sheet Thicknesses

Metal threaded inserts can be applied to mild steel, stainless steel, and aluminium sheet. Clinch-style inserts require the parent sheet to be softer or equal in hardness to the insert, and a minimum sheet thickness must be maintained to allow full material displacement into the clinch groove. Insert bodies are commonly available in carbon steel (zinc-plated), stainless steel, and brass, allowing selection based on corrosion environment and load rating.

When to Specify Threaded Inserts

Plan for threaded inserts at the design stage, before laser cutting begins. Holes must be sized precisely to the insert shank diameter, and insertion is scheduled after cutting and before or after folding depending on panel geometry. Specifying insert type, thread size, and material early avoids costly rework. Projects that benefit most include removable access panels, equipment enclosures, rack-mounted assemblies, and applications requiring clean panel faces.

Frequently Asked Questions About Metal Threaded Inserts

  • What Is the Difference Between a Clinch Nut and a Rivet Nut?

    A clinch nut presses into a punched hole, permanently locking in place. A rivet nut collapses from one side, suited to restricted rear access.

  • What Sheet Thickness Is Required for Self-Clinching Inserts?

    Minimum thickness varies by insert size and manufacturer specification. Samin Sheet Metal can advise on suitable thickness ranges for your insert and material combination.

  • Can Metal Threaded Inserts Be Used With Stainless Steel Sheet?

    Yes, provided the sheet retains sufficient ductility for the clinch displacement process. Stainless-bodied inserts may also be specified where full-assembly corrosion resistance is required.

  • Do Threaded Inserts Suit High-Vibration Applications?

    Self-clinching inserts suit vibration-prone assemblies because the mechanical lock resists rotation and loosening, making them preferable over tapped threads in guards and control panels.
