The PEMFLEX® design provides MIL-N-25027 locking performance without damaging mating threads. Thread sizes #2 to #10 and M2.5 to M5. All-metal, self-locking fasteners are available in steel, stainless steel, and aluminum.
A nylon hexagonal insert in PL (steel) and PLC (stainless steel) self-clinching nuts provides a reusable, non-metallic prevailing torque thread locking function. Thread sizes 4-40 to 10-32 and M3 to M5.
New PEM® S-RT free-running lock-nuts allow the mating screw to be spun on freely until a until clamp load is induced. Unlike other thread locking systems the screw runs freely until the final clamp load is reached and provides superior resistance to vibration.
