Natural Color Thread Repair M3 304SS Thread Inserts Screw Lock


Lock type wire thread insert is developed in ordinary type wire thread insert the original basis of new varieties. Type wire lock nut 1 to the middle portion of the pentagonal or hexagonal ring 2, when half of the bolt is threaded into the threaded hole, the bolt head hit the locking ring, when the wire thread insert tool by urging ratio other generally superior locking performance of the locking device, higher strength, while also repeated disassembly.

When the screw is screwed into the collar of the locking screw type wire, before entering the non-polygonal locking ring is loose, when the clamp ring screws entering the polygon, the polygon needs to distraction, deform the locking edge, at this time, to overcome the frictional force the screw into the screw to the locking edge. After this friction screw tightening screws do not make themselves loose, thereby locking in place of other ways.


The locking wire thread insert is a new variety developed on the original basis of the ordinary wire thread insert. There are 1 to 2 turns of pentagonal or hexagonal shape in the middle of the locking type wire screw sleeve. When the bolt is screwed halfway into the threaded hole, the head of the bolt hits the locking ring. Some other conventional locking devices have superior locking performance and higher strength, and can be disassembled repeatedly.
When the screw is screwed into the screw hole of the locking wire thread insert, it is loose before entering the polygonal locking ring. When the screw enters the polygonal locking ring, the polygon needs to be opened to deform the locking edge. At this time, when the screw is screwed in, the frictional force given to the screw by the locking edge must be overcome. After the screw is tightened, this friction force can prevent the screw from loosening by itself, thus replacing other locking methods.

1. The stainless steel thread has high strength.
2. The hardness of the screw surface can reach HRC43~50.
3. The surface accuracy can reach 2~4 μm.
4. Reduce the friction between the threaded surfaces. To
5. Increase the bearing capacity of the screws. To
6. Reduce the torque that the screw bears.
7. Make the load distribution on the entire rotating surface even.
8. Increase the load-carrying capacity of fasteners.


1. Quickly and effectively repair damaged threads on a variety of materials.

2. Enhance the thread strength on light materials, such as large and medium-sized non-ferrous metal castings, die castings and ductile ferrous metal base materials, as screw holes that are often screwed in and out.

3. It is especially suitable for use in environments requiring high-strength internal threads, with strong seismic and pull-out resistance. It has higher strength than commonly used wire thread inserts, and is firmly connected to the base body, and will not be separated from the base body even when working under shock or vibration environment.

4. Remedy the wrong hole and avoid reprocessing the wrong part.
