Wholesale supply of steel wire nut, screw jacket

wire thread insert feature

(1) free state diameter of wire thread insert into the screw diameter than the larger, steel wire nut assembly to be special torque wrench to make it smaller in diameter, into the have a good attack with a special wire tap screw, the bottles and then, steel wire nut produce similar expansion of the role of spring, so firmly fixed in the threaded hole, but never with the screw of the screw out and take out.

(2) to increase the carrying capacity of threaded connections and fatigue strength: steel wire nut to screw with the installation of wire thread insert tapped holes formed between the inner elastic connection, thus eliminating between internal and external thread The pitch and the tooth-type half-angle error can be provided so that each ring on the length of thread on the load being evenly distributed, thus strengthening the internal thread, and to vibration, it can improve the fatigue strength of threaded parts.

(3) Wear: steel wire nut from the extremely hard cold-rolled stainless steel wire precisely wound formed, spiral surface hardness up to HRC43 ~ 50, mirror like surface (roughness can be up to 2 ~ 4
