Introducing PEM® PEMFLEX® self-locking, self-clinching fasteners, engineered for enduring performance. Featuring a shoulder for enhanced functionality, these fasteners maintain their prevailing locking torque even after repeated use. The flexing action allows for efficient locking torque, while the flange ensures a secure installation. With thread locking performance meeting NASM25027 standards, these fasteners provide reliable attachment without protruding through the sheet. Available in steel, stainless steel, and aluminum, they offer high torque-out and pushout resistances. The innovative PEMFLEX design, with rugged semicircular flexing jaws, prevents loosening in harsh conditions and protects the screw threads. Trusted for their durability and ease of assembly, these fasteners are the ideal choice for a wide range of applications.
