The PEM® PEMFLEX® self-locking, self-clinching fasteners offer reliable performance with their unique design. Featuring a shoulder for enhanced functionality, these fasteners provide a secure fit with a flexing action that allows for repeated use and maintains effective prevailing locking torque. The flange ensures a positive stop during installation, while the all-metal construction in steel, stainless steel, or aluminum options caters to various application needs. Treated with a black dry film lubricant for better locking performance, these fasteners adhere to high industry standards for thread locking. The PEMFLEX design, with its rugged, semicircular flexing jaws, offers superior retention and prevents relaxation or loosening, even in severe service conditions. Additionally, the design protects the screw threads, minimizing the risk of damage and ensuring long-lasting durability. The self-clinching feature allows for fast and simple assembly, providing a secure attachment without protruding through the reverse side of the sheet. With high torque-out and pushout resistances, these fasteners are ideal for demanding industrial environments.
