What is a press nut?

A press nut is designed to be permanently installed in a sheet metal through a pre-drilled hole. It is mounted using a press at a speed that allows the metal to flow under the nut’s head, preventing it from loosening. A press nut should not be hammered into place. Press nuts are especially useful when a durable and strong threaded connection is needed in materials too thin to hold a thread on their own.

A press nut can often replace a regular nut, eliminating the need to handle both bolt and nut when tightening a joint. It can also replace a weld nut in many cases, avoiding the environmental issues associated with welding and ensuring the nut is positioned correctly. If the hole is correct, the nut is correctly seated.

In a controlled environment, with the right plastic material and a PT screw, it can work. However, we recommend installing a threaded insert in the plastic for a more secure joint. If you need to remove and re-tighten the screw multiple times, it is rarely advisable to screw directly into the plastic. A threaded insert provides a larger contact area and the thread can be used an unlimited number of times.

It is used to prevent a screw joint through plastic material from being over-tightened. Since plastic can deform when the joint is tightened, this deformation may cause the product to malfunction. Compression limiters can be installed cold, with heat, or molded into the plastic during the manufacturing process.
