TR Fastenings Launches New Wedge-Lock Nut

Making bolt security easier

As part of an ongoing drive for continual product development, leading global manufacturer and supplier TR Fastenings has launched a new wedge-lock nut.
The TR wedge-lock nut combines the proven 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 proven 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. 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 and also offers considerable reduction in assembly time and effort. Furthermore, 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.
Typical applications include high pressure valves and actuators, wind turbines, railway and wheel nuts for both road and rough terrain vehicles.
"The new TR Wedge-Lock nut is a great addition to our range of self-locking nuts,” comments Paul Standing, Commercial (Products) Manager at TR Fastenings. "This product range offers the perfect solution to our high end Automotive, Rail, Renewable Energy and Construction business sectors who are looking for components with additional safety and security features. Although it isn’t restricted to these sectors, it ensures that our range is as versatile as our customers need it to be."
