How do I choose between blind and through self-clinching standoffs?

Use blind standoffs when you need a closed interior (e.g., protecting electronics); choose through standoffs when a pass-through or stacking of panels/PCBs is required.

What are the key installation requirements for self-clinching fasteners?

Install with a press (not hammer) using flat anvils. The host sheet must be ductile and softer than the fastener, and meet the specified minimum thickness for the size/type selected.

Which material should I pick for corrosion resistance?

Stainless A2 suits most environments; choose A4 (316) for marine/chemical exposure. Zinc-plated carbon steel is cost-effective for indoor applications.

Can self-clinching fasteners be used in aluminium or stainless sheets?

Yes, provided the sheet is within the hardness and thickness limits for the specific fastener. Stainless-into-stainless is possible with the right grade and installation practice to avoid galling.

Self-Clinching Fasteners — Studs, Nuts, Pins & Standoffs

Self-clinching hardware provides strong, permanent threads or pilots in **thin sheet metal** without loose nuts or weld operations. Ideal for electronics, sheet-metal fabrication, HVAC, automotive, telecom and enclosure builds. We stock **steel, stainless (A2/A4)** and aluminium types with plain, zinc and black finishes. Select by sheet thickness, hardness and access (blind vs through).

How They Work

Knurl/undercut rings displace ductile sheet metal and lock mechanically.
Installation via press (not hammer) with flat anvils for square seating.
Require sheet softer than the fastener; minimum sheet thickness per type/size.

Materials / Finishes

Carbon steel, Stainless A2/A4, Aluminium
Plain oiled, Zinc (clear/yellow/black), Black oxide
Flush-head/low-profile variants available

Selection Tips

Check **sheet thickness range** for each size (stud/nut/standoff).
Choose **blind standoff** where interior must be closed.
Use **through standoff** for pass-through or stacking panels/PCBs.

Browse Self-Clinch by Type

Self-Clinching Studs

Provide a robust male thread permanently anchored in sheet metal. Available in steel/stainless with various head styles. Specify thread size and sheet thickness range for proper clinch.

Self-Clinching Nuts

Create strong female threads in thin sheet—fast assembly with one-side access. Options for flush-mount, high-torque and different material pairings.

Self-Clinching Pins

Quick-locating and captive pins for hinges, pivots and alignment points. Choose grooved/knurled styles and confirm required protrusion through mating parts.

Self-Clinching Blind Standoffs

Closed-end spacer giving a threaded stand-off without breakthrough—protects electronics and sealed enclosures. Great for PCB standoffs where back side must remain closed.

Self-Clinching Through Standoffs

Through-hole spacer for stacking panels or allowing a pass-through. Available in multiple lengths and threads; verify grip (sheet) range before selection.

Applications

Sheet-metal enclosures, PCB mounts, HVAC & appliances, automotive interiors, telecom racks, industrial panels and fixtures. Use **blind standoffs** when backside must be sealed; prefer **stainless** for high-corrosion areas; follow press-fit load and die/anvil recommendations.
