The Heico 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 proven Heico-Lock® principle of 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 by moving across each other and 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 2 component parts are fixed permanently in the correct position. The design makes the wedge lock nut perfect for use in hard to reach locations and also offers considerable reduction in assembly time and effort. As well as being easy, safe and fast to use (even for non-specialist users) the nut is totally re-usable without any loss of function.
The Wedge Lock Nut is an exciting addition to the Heico range that already includes the original Heico-Lock® washer and the innovative Ring-Lock system so why not contact the Heico team today to discuss your requirements further.
