A major benefit of rivet nuts are the variety of styles. Well not to be outdone, clinch nuts also come in a few standard styles that each have its own benefits.

Let’s take a look at different styles of clinch nuts:

ACN Series – High Strength Clinch Nut

High Strength Clinch Nut

ACN Clinch Nut

On this clinch nut, there are displacement lobes that force the sheet metal to flow into the locking groove when pressed in. This allows sheet metal to remain flat with no indentation and providing the nut with high push out and torque values. The base material remains flush.

This style of clinch nut is designed for thicker sheet metal applications from 2mm to 10mm thick, and is compatible with Class 8, 9, & 10 hardware depending on application requirements.

ASN Series — Serrated Style Clinching Nut Series

ASN Clinch Nut

ASN Clinch Nut

This clinch nut has extensive knurls that push into the material. During installation, sheet metal is formed into an undercut section on the nut collar by the die button and the knurled ring. As a result, the nut has high push out and torque values, and space requirement is minimal due to the small outer diameter and flat installation surface.

The ASN clinch nut can be used in sheet metal applications from 1.5mm to 10mm thick, and is compatible with Class 8, 9, & 10 hardware depending on application requirements.

ARN Series – Universal Clinch Nut

The ARN Series clinch nut is a unique style of clinch nut that has locking grooves to dig into the material when pressed in, while the neck part of the clinch nut is crimped over the base material using a special die, making the base material “almost flush.” Locking grooves are the clinch feature of the nut, providing high push out, pull through, and torque values, even in very thin sheet materials. The nut can be installed using several different installation methods depending on the sheet material thickness, hardness, and installation clearance.

Can be used in sheet metal from 0.4mm to 6mm thick, and is compatible with Class 8, 9, & 10 hardware depending on application requirements.

Custom Clinch Nuts

Some projects that require clinch nuts might need a higher tolerance grip range, or something that can bite into the material more, or a different coating. Sherex can design-in and manufacture special clinch nuts for your project. Be sure to look at our post Rivet Nuts vs Clinch Nuts to read the differences and similarities between the two fasteners!
