TR Fastenings Launches New Wedge-Lock Nut

The TR wedge-lock nut combines the locking ability of a washer combined with the ease of use of a flanged nut. This one piece design provides the customer with ease of use, effective bolt security and a reduction of assembly time and effort all in one.

The TR wedge-lock nut is supplied pre-assembled with the nut and washer combined in a captive and rotary way, and uses tension instead of friction to positively lock the bolt in place. The wedge shaped cams on the inside of the washers and radial teeth on the outside results in increased clamping force being applied during periods of vibration or dynamic load.

The external radial teeth embed into the mating surfaces when tightened while the internal cams react to any movement in the joint. As the height of these cams is greater than the pitch of the bolt thread, the increase in the height of these moving cams increases the clamping force on the joint, thus causing the bolt to self-lock.

The one-piece design eliminates the risk of misuse as the two component parts are fixed permanently in the correct position. The design makes the wedge-lock nut perfect for use in hard to reach locations. Furthermore, the nut is totally re-usable without any loss of function. Typical applications include high pressure valves and actuators, wind turbines, railway and wheel nuts.
