TR Self Clinch Low Profile Panel Fastener installation
1 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 
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 
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 
The serrations if properly installed will provide torsional (rotational) resistance. After installation the spigot joint should be flush with the sheet.
