LK-256-1MD
PEMFLEX® Self-locking, Self-clinching Fasteners - Types LK, LKA, LKS - Unified
The PEM® PEMFLEX® self-locking, self-clinching fasteners feature a shoulder for enhanced performance, providing a secure and durable locking torque. Designed for repeated use, the flexing action ensures reliable locking capabilities, while the flange offers a positive stop during installation. With a black dry film lubricant for improved locking performance, these fasteners are available in steel, stainless steel, and aluminum options. The innovative PEMFLEX design, with two semicircular flexing jaws, prevents relaxation and loosening in demanding applications, while protecting the screw threads. Perfect for high-torque environments, these fasteners guarantee permanent attachment with exceptional pushout and torque-out resistances. Meeting stringent NASM25027 specifications, they ensure reliability and longevity in assembly processes.
