The Tracksure Product

Tracksure’s award-winning locking device prevents unintentional nut loosening and offers infrastructure managers significant operational and cost benefits. Unlike other fasteners it can be simply maintained and does not require expensive capital equipment to install.

The Tracksure locking device:

  • A modified bolt with a reverse thread added to the end which accommodates both the original nut and the Tracksure locking nut
  • A locking nut is applied on to the reverse thread until it tightens against the original nut
  • A serrated steel locking cap then pushes down over both the original nut and the Tracksure nut, held in place with a spring 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 fail-safe bolt fixing.

The principle behind the device works with many different track and rolling stock applications. Examples include:

  • Brake/Retarder systems
  • Crossings
  • Tightly curved track
  • Temporary clamps & joints
  • Fishplates/Insulated joints

It can also be tailored for bespoke applications

It is suitable for retro-fitting to existing track and for OEM applications.
