Multi Piece Fastener L.L.C. was incorporated in 2019 with the express purpose of creating a new category of fastener. The design, trademarked as ForeverLok™, underwent rigorous testing to prove that it was a reliable anti-vibrational design. The tests required for the ForeverLok™ design were the most stringent, universally accepted tests. A testing facility was selected that had the requisite certifications. Three tests were conducted: a maximum torque test; the Din 25201-4 test; and the 1312-7 Military test. The fastener completed all testing by far exceeding all specified requirements.
