TR Self-Clinch Stud Installation Guide

This article provides a 4-point step-by-step storyboard style installation guide for the TR Self-Clinch stud.

The TR Self-Clinch stud design is based around the clinch nut features and installation principles but offers a male thread cut to customer length requirements.

 

Step:: 1  

Ensure the correct spigot length has been selected for sheet thickness being used.  

Select the appropriate hole size from the table below for the bush size required. Punch the hole diameter into the sheet material. 

 

Step:: 2  

Place the studs spigot end into the hole on the side opposite the mating face. So that the head serrations rest on the parent material.     

Ensure both plate and stud are aligned along the same axis. If not, the joint will be imperfect and mating threads will mis-align.   

 

Step:: 3 

Self Clinch Stud Step 3a Using a flat faced profiled punch, apply only sufficient pressure to ‘squeeze’ the stud head and its underhead tooth features into the parent sheet metal.    

 

 

 

 

 

 

 

Step:: 4  

The tooth locking ffeature if properly installed will provide torsional (rotational) resistance. After installation the spigot joint should be flush with the sheet metal.

 

 

 

Using the table below with reference to the specific size of the Clinch Stud, select the correct Hole size for the installation of the fastener.  

For the best dimensional accuracy and therefore performance, TR Fastenings recommends that all holes in the sheet metal application be punched.  

Note it is essential that the recommended Hole tolerances be observed.
