What is the locking T nuts?

Locking T nut is friction between the nuts and bolts of self-locking.But in the dynamic load will reduce the reliability of the self-locking.In some important occasions we will take some prevention measures, to ensure the reliability of the nut lock.Lock nut is one kind of locking measures, at the same time it also has a lot of kinds: 1. Special locknut, need and a locking washers are used together.Dedicated locknut is not hexagonal nut, but a round nut, the nut on the circumference of a circle with three, four, six or eight gap (depending on the size of nut and manufacturers products vary), these a few gap is the focus of tightening tools, and locking washers bayonet card into place. 2. Within the cylindrical surface to the nut round thread runs through the thread hole is drilled surface (usually 2, outer circle like 90 distribution), used to screw into the small diameter countersunk head screws, the purpose is to put a thread under direction of the centripetal force, prevent loosen lock nut.Sales on the market at present the quality of a good lock nut on the nut of the inner circle surface with consistent with the lock nut thread copper pieces, used to avoid the radial head screw direct contact with the locked thread and damage to the latter. 3. The LOCK nut is consists of two parts, each part has staggered CAM, due to internal wedge Angle design of slope Angle is greater than the bolt nut, the combined tightly bite into a whole, when the vibration occurs, DISC - LOCK raised portion are performed.the locknut, raising tension, so as to achieve the perfect effect of locking.
