| The Phil-Lok positive-locking fastener employs a simple yet unique patented coupling mechanism that acts as a physical stop whereby the nut is rotationally fixed relative to the bolt to inhibit rotation of the nut. This inovative design has been recognized by the History Channel's Modern Marvels in their recent 2007 Invent Now challenge by receiving an honorable mention award! There were 100 honorable mentions along with 20 semi-finalists, 4 finalists and 1 winner out of more than 3300 entrants! The entries were inventions represented from many different industries. We are pleased to recieve this award and to be recognized for our contribution to industry as a Modern Marvel!!! Come visit us at www.phil-lok.com to learn more about this exciting new fastener. This site has been established to promote the "The Phil-Lok positive-locking fastener", to encourage the practice of "positive-locking fasteners" and to demonstrate the advantages of "positive-locking" over other traditional vibration resistant fastener practices and products available on the market today. A vibration resistant fastener uses increased frictional forces to prevent nut loosening where a vibration proof (positive-locking) fastener actually uses a physical stop or barrier to prevent nut loosening.
