How to prevent the biting of high strength nuts? 1. Before use, choose a relatively good product before use, and then meet the connection needs. Generally, consumers will choose the appropriate length of the screw thread. Generally, it is best to show one or two pitches after tightening the thread. In addition, it is necessary to carefully check the condition of threads. The rougher thread production can often lead to locking phenomenon in use; if there are iron chips, rust and other dirt in the thread, it will also increase the probability of locking phenomenon. In addition, it can also be used to lubricate the corresponding threads before use. In fastener products such as nuts, butter, mica and other products are generally used as lubricants to prevent the occurrence of biting phenomenon. 2. When tightening, we usually choose torsion wrench or sleeve wrench. When tightening, we should not use too much force, make appropriate arrangements, and do not appear too fast. Too fast will increase friction and cause temperature to rise instantaneously, thus destroying the oxide layer on the surface of stainless steel. At the same time, gaskets can also be placed between nuts and connecting parts. As long as these problems are noticed, the locking phenomenon of stainless steel fasteners will be greatly reduced and the service life of fasteners will be prolonged.
