The Zhuocheng Self Clinch Nut can be installed into a pre-punched or pre-drilled hole using a press capable of a squeezing action, causing the parent material to flow into the specially designed under head configuration offering a load bearing and torque resistant joint.
Step 1
Ensure the correct spigot length has been selected for sheet thickness being used. Select the appropriate hole size from the table below for the bush size required. Punch the hole diameter into the sheet.
Step 2
Place the nut spigot end up into the hole on the anvil, so that sheet rests on the serrations. Ensure both sheet and nut are aligned along the same axis. If the sheet is not seated ‘square’ on the nut, the joint will be imperfect and mating threads will misalign.
Step 3
Using a punch, apply only sufficient pressure to ‘squeeze’ the nut serrations into the parent sheet.
Step 4
The serrations if properly installed will provide torsional (rotational) resistance. After installation the spigot joint should be flush with the sheet.
