Multi Piece Fastener has won a 2021 Fastener Innovation Award for its ForeverLok fastener design from WorldwideFastenerSources.com, a comprehensive source for fasteners. The award, which is in its third year, recognizes groundbreaking design innovation in engineered fasteners today that will become a standard in future years.
The Fastener Innovation Award is one of three prestigious awards in the fastener industry, along with the Soaring Eagle Awards from the Industrial Fastener Institute, and the Fastener Hall of Fame awards from the International Fastener Expo.
“It is an honor to be named a winner of the Fastener Innovation Award,” said Earl Size, founder of Multi Piece Fastener. “As engineers incorporate innovative fasteners as part of the design process to solve challenging issues of vibration, we are proud to be part of the solution.”
In industries such as aerospace, marine, defense, 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 design involves three items: a central threaded fastener, a threaded intermediate fastener, and a retaining fastener.
Essentially, the fastener system holds the nut in place to physically prevent it from loosening. The locking design does not use special pins, bolts, or tools to install or remove the nut. Only common tools are needed to fasten/unfasten.
International testing standards found that the ForeverLok:
• Provided results from the military vibrational test (NASM 1312-7) that exceeded typical requirements by over 14 times, retaining an unprecedented 93.5% of its original torque.
• Retained 89% of torque surpassing the retention pass specification of the DIN 25201-4 test.
• Offers an estimated 50% higher recommended torque rating than the recommended torque rating for the 1/2″-grade, 8-bolt used in the break torque testing.
This means the ForeverLok could potentially configured as a smaller, lighter, and more compact fastener while providing a comparable torque value.
