The PEM® PEMFLEX® self-locking, self-clinching fasteners are engineered for reliable and repeated use, offering effective prevailing locking torque. Featuring a shoulder for enhanced performance, these fasteners allow for flexing action, ensuring consistent locking torque over time. With a flange providing a positive stop during installation, they guarantee secure attachment without protruding through the sheet. Made from 300 Series Stainless Steel, these fasteners meet RoHS compliance standards and are designed for high torque-out and pushout resistances. The PEMFLEX design, with two rugged, semicircular flexing jaws, prevents relaxation and loosening in severe service, while protecting the screw threads. Suitable for a wide range of applications, these fasteners offer durability and performance in assembly processes.
