TR Self Clinch Pin installation

 
  • Punch or drill the mounting hole. Do not deburr the hole or perform any other secondary operations
  • Place fastener into anvil recess then place sheet over the fastener spigot
  • Apply squeezing force, ensuring that the punch and anvil surfaces are parallel, until the retainer shoulder makes contact with the face of the sheet
 
1 Step 1 Self Clinch Pin Step 1

Select the appropriate hole size from the table below for the pin size required. Punch the hole diameter into the sheet and place on top of the appropriate anvil.

2 Step 2 Self Clinch Pin Step 2

Place the pin 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 misalign. 

3 Step 3 Self Clinch Pin Step 3

Using a flat faced punch, apply only sufficient pressure to ‘squeeze’ the pin head and its under head tooth features into the parent sheet.

4 Step 4 Self Clinch Pin Step 4

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