Fine Thread Steel Screw Sleeve Screw Lock Inserts Sdt14 * 1.5 * 1d

Manufacturer of lock type steel wire thread with complete specifications ST14*2

When the screw enters the polygon locking ring, the polygon shall be opened to deform the locking edge.

At this time, the screw shall overcome the friction force of the locking edge on the screw The locking type is to add one or more turns of locking ring on the basis of the common type, and tighten and loosen the fastening screw.

There are 1-2 circles of pentagon or hexagon in the middle part of the locking type steel wire bolt sleeve. When the bolt is screwed into the half of the threaded hole, the head of the bolt touches the locking ring. At this time, the locking performance of the steel wire bolt sleeve by applying force through the tool is superior and the strength is higher than that of other common locking devices. At the same time, it can be disassembled repeatedly.
