PEM® Fasteners by PennEngineering®
Innovative Solutions for Strong, Reliable Connections
PEM fasteners deliver precision-engineered solutions for creating strong, reusable threads and mounting points in thin materials like sheet metal and printed circuit boards (PCBs). Using technologies such as self-clinching, broaching, flaring, surface mounting, and welding, PEM fasteners ensure durability and reliability in both ductile and non-ductile materials.
