Self-Clinching Standoff / Rivet Stud

Self-clinching standoff pressed into sheet from one side, leaving a threaded column that another part can be fixed to.

Product overviewOverview

A rivet stud is the mirror image of a rivet nut: it provides an external thread instead of an internal one. The standoff is held by displaced sheet material flowing into an undercut, not by friction, so push-out and torque-out depend on hole size and on sheet hardness rather than on how hard it is pressed. In hard or thin sheet the undercut fills poorly and the part works loose under vibration.

Material: Carbon Steel / Stainless Steel. It is set from one side with a rivet-stud tool.

Key featuresFeatures

Held by sheet material in the undercut, so hole size is critical.
No spatter or heat-affected zone on the visible face.
Single-side installation creates an external thread without welding.
Thread and bulge formed together; perpendicularity set by the tool nose.

Typical applicationsApplications

Appliance panel mounting
Elevator and access-control hardware
Battery pack structures

Selection notesSelection

Check sheet hardness and thickness against the standoff range; a hole that is too large leaves the undercut empty and reduces both push-out and torque-out.

Frequently asked questionsFAQ

Why does a clinch standoff spin in service?

The undercut was not filled, usually because the hole was oversize or the sheet was too hard. Once it spins, the joint cannot be recovered by re-pressing; the part has to be replaced.

What matters during installation of the Self-Clinching Standoff / Rivet Stud?

Set it from one side with a rivet-stud tool. Held by sheet material in the undercut, so hole size is critical.
