PEMFLEX® Self-locking, Self-clinching Fasteners - Types LK, LKA, LKS - Unified
The PEM® PEMFLEX® self-locking, self-clinching fasteners offer reliable performance with their unique design. Featuring a shoulder for enhanced functionality, these fasteners ensure repeated use and effective prevailing locking torque. The flexing action allows for ease of use while maintaining secure locking. With a flange for added stability during installation, these fasteners boast high torque-out and pushout resistances. Available in steel, stainless steel, and aluminum, they are treated with a black dry film lubricant for improved locking performance. The PEMFLEX design, with its rugged semicircular flexing jaws, prevents relaxation and loosening in demanding applications, while also protecting the screw threads. Trusted for their durability and efficiency, these fasteners provide a simple and effective solution for assembly needs.
