PEM® PEMFLEX® self-locking, self-clinching fasteners offer reliable performance with a unique design that ensures repeated use and effective prevailing locking torque. Featuring a shoulder for enhanced functionality, these fasteners boast a flexing action that maintains locking torque over time. The flange provides a positive stop during installation, while the all-metal construction in steel, stainless steel, or aluminum options ensures durability. With a black dry film lubricant for improved locking performance in steel and stainless steel variants, these fasteners are designed to withstand severe service conditions. The innovative PEMFLEX design, utilizing two rugged, semicircular flexing jaws, not only enhances retention but also protects screw threads, minimizing the risk of damage. Ideal for applications requiring high torque-out and pushout resistances, these fasteners guarantee secure and permanent attachment.
