Shock and vibration proof ReLok™ fasteners by DuraForce

Miller Ingenuity is the rail industry’s exclusive distributor of DuraForce Fasteners.

Customers frequently come to us and complain that they are spending most of their time tightening up track bolts that become loose from track vehicle vibrations. Our ReLok™ fastener system, a vibration-proof, self-locking nut, can significantly increase a customer’s hardware lifecycle and reduce maintenance labor costs. Its unique design features the annulus of the nut being forced into the collar during vibration movement and that captures, retains and delivers the energy back to the joint to ultimacy deflect shock and vibration. In addition, even though the system is a locking fastener, customers can reuse the fastener for multiple installations and can remove the fastener using the same amount of force that was needed to tighten it up.

The two-part ReLok™ system was recently enhanced to now feature a unitized version that minimizes parts for inventory and makes installation easier for maintenance crews.

The system has been tested at a well-known Diamond test location in Bremen, GA. The enormous lateral forces of trains on this crossing create a very severe condition by itself and the addition of the constant cyclical motion of automobiles running across this intersection have caused all other fasteners to fail quickly. ReLok™ has held strong at a location that was previously under constant monitoring and upkeep. The fastener has recently been purchased by two Class 1’s new Diamond installations.
