LKA-440-2
PEMFLEX® Self-locking, Self-clinching Fasteners - Types LK, LKA, LKS - Unified
PEM® PEMFLEX® self-locking, self-clinching fasteners feature a shoulder for enhanced performance and a flexing action that allows for repeated use with effective prevailing locking torque. The flange provides a positive stop during installation, ensuring secure attachment. With the thread locking performance meeting NASM25027 specifications, these fasteners are reliable and easy to assemble. Available in steel, stainless steel, and aluminum, they offer high torque-out and pushout resistances. The PEMFLEX design, with two rugged flexing jaws, prevents relaxation and loosening in severe service conditions, while also protecting screw threads. Trusted for their durability and retention, these fasteners are ideal for a wide range of applications.
