Introducing PEM® PEMFLEX® self-locking, self-clinching fasteners, engineered for reliable and efficient performance. Featuring a shoulder design for enhanced functionality, these fasteners offer a flexing action that allows for repeated use without compromising locking torque. The flange ensures a secure installation, while the thread locking performance meets stringent NASM25027 specifications. Available in steel, stainless steel, and aluminum variants, with a black dry film lubricant for improved locking performance, these fasteners guarantee lasting attachment with high torque-out and pushout resistances. The innovative PEMFLEX design, with its rugged semicircular flexing jaws, prevents relaxation and thread damage, making it the ideal choice for demanding applications.
