The Tracksure Locking Device comes in a range of sizes from M12 upwards. It is suitable for retro-fitting to existing track and for OEM applications. It can also be tailored for bespoke applications.
A modified bolt with end reverse-thread, accommodating both the original nut and Tracksure locking nut.
A locking nut is applied onto the reverse thread until it tightens against the original nut.
A serrated steel locking cap pushes down over both the original nut and the Tracksure nut, which is held in place with a string clip.
If the original nut starts to loosen, even microscopically, the locking nut tightens on the reverse thread with the locking cover combining both actions, ensuring a failsafe bolt fixing.
The device is supplied for Brake Retarder Systems, Breather Switches, Crossings, Tightly Curved Track, Temporary Clamps and Joints, and Fishplates / Insulated Joints. Our product has been extensively tested and approved by many rail infrastructure companies throughout the world, as well as independently tested.
