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 allow for flexing action, ensuring optimal locking torque with each use. The flange provides a positive stop during installation, while the all-metal construction (available in steel, stainless steel, and aluminum) guarantees durability. With black dry film lubricant on steel and stainless steel variants, these fasteners offer superior locking performance. The PEMFLEX design, with two rugged, semicircular flexing jaws, prevents relaxation and loosening in severe service, while also protecting screw threads. Ideal for applications requiring high torque-out and pushout resistances, these fasteners provide secure, permanent attachment without protruding through the sheet. Trust in the PEMFLEX design for fast, simple assembly and long-lasting performance.
