The PEM® PEMFLEX® self-locking, self-clinching fasteners ensure reliable performance with their innovative design. Featuring a shoulder for enhanced functionality, these fasteners offer exceptional locking torque that remains effective through repeated use. The flexing action allows for easy installation and ensures a secure fit, while the flange provides a positive stop during assembly. With their all-metal construction available in steel, stainless steel, and aluminum, these fasteners are durable and versatile. Treated with a black dry film lubricant for improved locking performance, they meet high standards for thread locking. The PEMFLEX design, with its rugged semicircular flexing jaws, offers superior retention and prevents loosening even in harsh conditions, safeguarding the screw threads. Their simple yet robust construction makes them ideal for a wide range of applications.
