LK-256-2MD
PEMFLEX® Self-locking, Self-clinching Fasteners - Types LK, LKA, LKS - Unified
PEM® PEMFLEX® self-locking, self-clinching fasteners are engineered for reliable and durable performance. Featuring a shoulder design for enhanced functionality, these fasteners offer a flexing action that allows for repeated use while maintaining effective locking torque. The flange ensures a positive stop during installation, while the black dry film lubricant treatment on steel and stainless steel variants (Types LK and LKS) improves locking performance. The PEMFLEX design, with two rugged, semicircular flexing jaws, provides superior retention, preventing relaxation and loosening even in demanding applications. With high torque-out and pushout resistances, these fasteners offer secure and permanent attachment without protruding through the sheet. Suitable for steel, stainless steel, and aluminum materials, they meet stringent quality standards and are RoHS compliant. Trust in PEM® PEMFLEX® fasteners for efficient and long-lasting assembly solutions.
