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