What is a self-locking rivet nut?

The open semi-hex Deform-Nut® rivet nut with threadlocking feature, developed by Specialinsert®, is available in two versions in steel zinc plating as well as in stainless steel316: the reduced head ETFM/A and the flat head ETC/A. Both models are fitted with a nylon locking ring inside the thread, ensuring that the fastener remains secure and does not loosen under vibration. Reliable and reusable, the locking should be tested with the specific screw used in your application in order to get an idea how many times it fonctions.

Easy to install with either manual rivet-nut tool or a electric tool, the Deform-Nut® reshapes behind the sheet metal to create a strong, vibration-resistant and lasting connection.

Description

A rivet nut with self-locking thread?

The semi-hexagonal open rivet nut with selflocking nylon ring is an exclusive solution from Specialinsert® wich provides a innerthread in thin sheet and garantuees one time self-locking at the same time!

The Deform-Nut® ETC/A type has a flat collar and the ETFM/A type a reduced head wich can provide an innerthread in sheet metal from 0,5 up to 6,0mm.

How to mount a rivet nut?

First you choose the right grip range and the right metric innerthread for your application (attention on the needed space behind the sheet!) and then you get a manual or pneumatic tool for rivet nuts.

When you lazered the needed hole size for the semi hex self-locking rivet nut, you screw the rivet nut on the outer thread of the tool without touching the nylon ring and pull back the innerthread towards the collar.

This way, the rivet nut will deform itself and grip the thin sheet.

Simply unscrew the outer thread from the semi hex self-locking rivet nut and you're done! Now, the screw can go trough the nylon ring as well and be locked so that vibrations don't loosen the fastening.

Both are possible in steel zinc plating and stainless steel 316, but recommend to check the availability since they're not always on stock.
