The ForeverLok combines right and left-handed threads to cancel vibrational loosening.
Multi Piece Fastener L.L.C. (MPF) has announced its newest version of the patented ForeverLok design. The new ForeverLok Bolt design features a recessed area in the head of the bolt to receive a retaining screw. The opposite threaded retaining screw passes through the bolt to connect to the base material, preventing loosening.
“This is an exciting product for Multi Piece Fastener,” shared Multi Piece Fastener founder and CEO, Earl Size. “This gives MPF the advantage of servicing nut and bolt applications, as well as bolt only applications. The ForeverLok characteristics allow us extraordinary opportunities to serve our clients. Imagination and innovation are how we bring solutions to the marketplace.”
In industries such as aerospace, marine, defence, construction, heavy equipment, oil and gas production, wind turbines, and automotive, tremendous repetitive forces contribute to fastener self-loosening. To prevent such self-loosening, the ForeverLok Bolt design involves three items: a central threaded fastener, a threaded intermediate base, and a retaining fastener. Only common tools are needed to fasten/unfasten.
The international testing standards features include:
- The ForeverLok design results on the military vibrational test (NASM 1312-7) exceeded requirements by over 14 times and retained an unprecedented 93.5% of its original torque.
- The ForeverLok design fastener retained 89% of torque surpassing the retention pass specification of the DIN 25201-4 test.
The ForeverLok design is available for licensing.
