A swage nut or self-clinching nut is a type of nut or threaded insert is used on sheet metal. A PEM nut is a popular brand name by Penn Engineering & Manufacturing Corp, which is often used generically for swage nuts from any manufacturer. It permanently anchors itself to the sheet metal by swaging the surrounding material. Generally, the swage nut is made of a hard metal such as stainless steel, which is inserted into a pre-drilled hole in softer ductile material such as aluminum. The inserted shank has three diameters: the main shaft which fits the hole closely, a thin smaller-diameter undercut, and a larger-diameter serrated clinching ring. Forcing the clinching ring into a softer material, with an arbor press or by tightening a screw through the hole, causes it to plastically deform (swage) into the annular recess in the shank. This locks the nut into the hole. The knurling on the clinching ring is not necessary for this step but prevents the nut from rotating after installation. This is a popular method for adding strong, load-bearing threads to a relatively thin piece of soft sheet metal. Ever Hardware provides custom-made fasteners and customizable packaging.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent self-clinching nut rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc.
