TR Self Clinch Recess Panel Fastener 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 Recess Panel Fastener Step 1

Select the appropriate hole size from the table below for the fastener size required. Punch the hole diameter into the sheet. Place fastener into anvil recess.

2 Step 2 Recess Panel Fastener Step 2

Place the sheet over the fastener spigot so that it rests on the fastener serrations. Ensure both plate and fastener are aligned along the same axis.

3 Step 3 Recess Panel Fastener Step 3

Apply squeezing force, ensuring that the profiled punch and anvil surfaces are parallel, until the retainer shoulder makes contact with the face of the sheet.

4 Step 4 Recess Panel Fastener Step 4

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