The unique design of PEM self-rive nuts, studs and fasteners published by Penn Engineering in the United States can be used for the assembly of sheet metal edges without compromising the matching sheet metal or fasteners. Its engineering design effectively shortens the minimum distance between the centerline of the hole and the edge of the sheet metal when riveting, providing an ideal solution when the fastener environment is limited. Once installed, the tough, durable and reusable metal threads are ready to be joined to other hardware, and can be repeatedly disassembled and re-disposed without affecting fastener or thread integrity, reliability and performance. Assembly.

These rivet fasteners will eventually lock into a permanent assembly that will not spin, loosen, fall, or cause problems in action. The PEM SMPSTM self-rivet nut is made of highly corrosion resistant 300 series stainless steel and can be permanently mounted on (0.64 mm or thicker) ultra-thin steel or aluminum. Its smaller diameter (5.6 mm) and lower height (1.4 mm) provide a complete low head fastener product solution with the center of the fasteners closer to the edge of the sheet metal to 3.7 mm. Thread sizes range from #2-56 to #6-32, from M2.5 to M3.5.

PEM FHLTM (steel) and FHLSTM (stainless steel) self-staking studs have a head that is not easily displaced, so the closest distance to the aluminum or iron plate edge can be increased by 50% compared to other standard products. At the same time, there will be no bulging at the edge of the sheet metal. The carrying sheet metal can also be as thin as 1 mm. Thread sizes range from #2-56 to #10-32, from M2.5 to M5.

PEM DSOSTM self-riveting stainless steel threaded fasteners (also available in steel) are used to block or stack components during assembly. It can be installed in a thin steel or aluminum sheet metal of 0.94 mm, and the distance from the edge of the gold plate can be as close as 3.2 mm. This fastener is available in two lengths with thread sizes #4-40 and M3. In addition to these riveted product solutions, PEM's solar-patterned fasteners are also available for riveting applications close to the edge of the part.
