Vibration nut looosening is a challenge known to engineers in many industries. Problems range from a minor inconvenience to a severe safety or operational difficulty, and in these latter cases the unique LD99 technology offers maximum benefits.
The patented LD99 consists of:
- A modified bolt with a reverse thread added. This accommodates both the original nut and the LD99 locking nut or stud
- The reverse thread can be added externally (a) or internally (b) and always consists of a new modified bolt
- A locking stud or nut is applied using 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 locking nut or stud, thereby maintaining a secure fixing
If the original nut should start to loosen (even microscopically) the locking nut or stud tightens against the original nut on the reverse thread with the locking cover combining both actions, ensuring a fail-safe bolt fixing.
The LD99 comes in a numberof sizes from M12 upwards and can be designed for bespoke applications.
The device can be specified as new and/or retro-fitted.
