Long-Lok's self-locking and self-sealing fastener processes have helped engineers solve threaded component fastening problems for more than 50 years. Long-Lok Fasteners Corporation was founded in 1957, in Los Angeles. Its initial mission was to exploit its newly-developed Long-Lok® process, which used a thin nylon strip to make a male-threaded fastener self-locking. At that time, this technology's primary application was in the aerospace industry, where the risk of bolts shaking loose was unacceptably high. Long-Lok has been known -- from the beginning -- as the company engineers count on to solve their vibration problems.
In the ensuing years, Long-Lok pioneered a variety of self-locking and self-sealing processes, resulting in the 9 varieties we offer today.
We are ISO 9001:2008 and AS 9100 certified. See our certificate.
