Long-Lok

Long-Lok logo

Long-Lok is the Engineered Fastener Company that makes self-locking fasteners and self-sealing fasteners. Long-Lok's self-locking fasteners and processes have helped engineers solve fastening problems with threaded components for nearly 50 years. The Long-Lok Poly-Lok process is by far the most reliable high temperature self-locking patch-type process in the world. Dual-Lok and Omni-Lok were developed for jet engine usage where heat and vibration are well above anything any other company could handle.
