Product overviewOverview

A self-clinching nut is held by cold flow, not by thread friction. Thin sheet gives the undercut little material to work with, and vibration adds a load the joint was not designed for. The anti-loosening feature acts on the thread side, so it does not compensate for a weak clinch; both have to be right.

Material: Carbon Steel / Stainless Steel. It is pressed into a prepared hole with a clinching press, working from one side.

Key featuresFeatures

Anti-loosening on the thread does not compensate for a weak clinch.
Zinc-plated carbon steel or stainless; thin-sheet series for 0.5–1.2 mm panels.
Short, standard and long bodies so the groove fills completely in each thickness.
Annular undercut and knurl: sheet metal flows in to form a mechanical interlock.

Typical applicationsApplications

Battery pack enclosures
Appliance and elevator control boxes
Instrument housings

Selection notesSelection

Hole diameter follows the thickness and material table; stainless sheet needs a slightly larger hole and more press force.

Frequently asked questionsFAQ

Does an anti-loosening nut fix a loose clinch?

No. The locking feature acts on the bolt thread, while a loose nut moves in the sheet. Push-out and torque-out still have to be verified on the actual gauge.

What matters during installation of the Ultra-Thin Anti-Loosening Self-Clinching Nut?

Press it into a prepared hole with a clinching press, working from one side. Anti-loosening on the thread does not compensate for a weak clinch.
