Stainless Steel A2-70 Polished Hexagon Nut 

The purpose of cap nut is as follows: (1) the cap nut and the stainless steel hexagon slotted nut are matched with a split pin, and the screw bolt with holes is used to bear vibration and alternating load, which can prevent the nut from loosening. (2) for cap nut with insert, the insert can screw out the internal thread by tightening the nut, which can prevent loosening and has good elasticity.

Its characteristic is that it is not easy to slip when clamping the main nut with spanner, but it can only be assembled and disassembled with adjustable spanner, solid spanner, dual-purpose spanner (open part) or special square hole socket spanner. It is mostly used in rough and simple components. (4) the cap nut can be used when the thread of bolt end needs to be covered. (5) cap nut can be used in tooling.
