The PEM® PEMFLEX® self-locking, self-clinching fasteners are designed for reliable and repeated use, offering effective prevailing locking torque. Featuring a shoulder for enhanced performance, these fasteners have a flexing action that allows for secure locking torque over time. With a flange providing a positive stop during installation, they ensure a sturdy attachment. The all-metal construction, available in steel, stainless steel, and aluminum, guarantees durability. Treated with a black dry film lubricant for improved locking performance, these fasteners feature a rugged PEMFLEX design with two semicircular flexing jaws, preventing relaxation and loosening in demanding applications. The design also protects the screw threads, minimizing the risk of damage. Trusted for their simplicity and efficiency in assembly, these fasteners are ideal for applications requiring high torque-out and pushout resistances, meeting RoHS compliance standards.
