We are a self-locking self-sealing fastener processes have helped engineers solve threaded component fastening problems for 50 years. Founded in 1957, in Los Angeles, our initial mission was to exploit our newly-developed process, which used a thin nylon strip to make a male-threaded fastener self-locking. At that time, this technologys primary application was in the aerospace industry, where the risk of bolts shaking loose was high, but unacceptable. We have been known -- from the beginning -- as the company engineers count on to solve their vibration problems. In the ensuing years, we pioneered a variety of self-locking and self-sealing processes, resulting in the 9 varieties we offer today. We are ISO 9001:2000 and AS 9100 certified.
