The PEM® PEMFLEX® self-locking, self-clinching fasteners offer reliable performance with their unique design. Featuring a shoulder for enhanced functionality, these fasteners provide a secure hold with effective prevailing locking torque. Their flexing action allows for repeated use without compromising locking performance, while the flange ensures a positive stop during installation. With all-metal construction available in steel, stainless steel, and aluminum, they are versatile for various applications. Treated with a black dry film lubricant for improved locking performance, these fasteners guarantee long-lasting durability. The PEMFLEX design, utilizing two rugged flexing jaws, prevents relaxation and loosening in severe service conditions, ensuring optimal thread protection and retention. Their easy assembly and high torque-out and pushout resistances make them a preferred choice for industrial use.
