High strength nuts are steel used for fasteners. They are produced by cold heading process and have high interchangeability. Because it is formed by metal plastic processing at room temperature, the deformation of each component is large and the deformation speed is fast. Therefore, the performance requirements of raw materials for high-strength nuts are very strict. Buy high-strength nuts for professional manufacturers. Our products are rich, high quality, and reliable.
They are the same as nuts. The difference between high-strength nuts and ordinary nuts is still great. Let us tell you below:
Common hexagon nuts have three disadvantages in bolt support technology:
(1) When the ordinary nut is equipped with grade steel bar, the maximum failure stress of the internal thread of the nut is less than 70% of the steel bar. The first failure of the internal thread of the nut leads to the waste of rod materials and the increase of unsafe factors.
(2) If ordinary nuts are used, a step of removing the nuts will be added when installing the bolts, which will prolong the working time and reduce the working efficiency.
(3) When ordinary nuts vibrate and vibrate underground, sometimes the steel wire will retract, causing the anchor force of the bolt to drop and accelerating the deformation of the roof.
Features of high-strength nuts:
(1) Easy to install; Integrity. No washing machine required; Easy to disassemble; Reusable medium carbon steel is used to make materials. Simple connection structure, good mechanical performance, removable, anti fatigue, and not loose under dynamic load. This is a promising connection method.
(2) The high-strength nut is used to tighten the special wrench nut, so that the bolt can generate a huge controllable pre tightening force through the nut and buffer plate, and apply the same pre tightening force to the joint. Under the pre pressure, there will be more friction along the connector surface. Obviously, as long as the axial force is less than the friction force, the parts will not slide and the connection will not be damaged. This is the principle of high-strength nut connection.
