UK-based Tracksure, a wholly-owned subsidiary of Wheelsure Holdings Ltd., and U.S.-based L.B. Foster Co. concluded an exclusive distribution agreement that authorizes L.B. Foster to sell the Tracksure fastener range throughout North America.

The Tracksure range of specialist rail fasteners are based on a unique patented technology that prevents nuts loosening through vibration and settlement and offer railroad managers significant safety and operational benefits.

Tracksure's range is suitable for any railroad application where vibration loosening and joint settlement leads to a constant safety and maintenance challenge. The Tracksure kit features a modified bolt with a left-hand thread added, which in turn accommodates a locking nut and a stainless serrated locking cover.

After torqueing the original nut to the accepted standards, the left-hand locking nut is tightened against it on the opposite thread. The Locking Cover is then applied to both nuts and the opposite threads under the cover prevent any movement or loosening. The patented technology, which is widely used and approved in Europe, is simple to install and entirely serviceable.
