Frequently Asked Questions
What is a self-clinching nut?
A self-clinching nut (often referred to as a PEM nut) is a threaded fastener that, when pressed into ductile metal sheet material, displaces the host material around the mounting hole, locking the nut securely in place.
What materials are suitable for installing self-clinching nuts?
They are designed to be installed in thin, ductile metal sheets, including carbon steel, stainless steel, and aluminum. The sheet hardness must be lower than the hardness of the nut for proper installation.
Do self-clinching nuts require welding or tapping?
No. One of the main advantages of self-clinching nuts is that they require no welding or tapping. They are simply pressed into pre-punched or drilled holes using a standard press.
What size ranges do you provide?
We offer metric sizes from M2 up to M12, and unified/inch sizes from #2-56 up to 1/2". Custom sizes and lengths can also be manufactured according to your specifications.
What is the typical lead time for an order?
Our standard lead time is between 7 to 30 days. This depends heavily on the total order volume, material availability, and whether the order requires custom specifications.
