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 material. 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 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 metal.
