PEM® PEMFLEX® self-locking, self-clinching fasteners are engineered for reliable performance, featuring a shoulder design that enhances functionality. With a unique flexing action, they provide secure locking torque even after repeated use. The flange ensures a precise stop during installation, while the black dry film lubricant treatment (for steel and stainless steel variants) improves locking performance. The innovative PEMFLEX design, with two robust flexing jaws, offers superior retention and prevents loosening in demanding applications. These fasteners provide permanent attachment with high torque-out and pushout resistances, ensuring durable and efficient assembly. Available in steel, stainless steel, and aluminum, they meet stringent quality standards for reliable performance.
