PEM® PEMFLEX® self-locking, self-clinching fasteners are engineered for repeated use, delivering reliable prevailing locking torque. Featuring a shoulder for enhanced performance, these fasteners boast a flexing action that ensures effective locking torque over time. With a flange providing a positive stop during installation, they offer ease of assembly. Types LK, LKA, and LKS, treated with a black dry film lubricant for improved locking performance, meet stringent NASM25027 specifications. The innovative PEMFLEX design, utilizing two robust flexing jaws, guarantees long-term retention and prevents loosening even in harsh conditions. Suitable for steel, stainless steel, and aluminum applications, these fasteners provide secure attachment with high torque-out and pushout resistances.
