Information 

Type wire lock nut threaded fastener is a new, high-precision stainless steel wire is precisely machined rhombic cross section made of a spring-like member concentric with and external thread. Type wire lock nut to increase the turn or several turns in the locking ring on the basis of the ordinary type.
Type wire lock nut (Helicoil Free-Running Inserts) as compared with conventional steel wire thread insert wherein the polygonal portion having one or more loops of the locking ring, which can be screwed a screw, screwed in the screw thread A strong elastic force is generated on the upper part to ensure reliable locking and effectively avoid the loosening of the fastener due to vibration. Portion above the locking ring can be screwed into the screw by hand, after the necessary lock ring is screwed onto a screw to mechanically loaded. The locking wire thread insert has multiple disassembly and assembly without reducing the tightening torque of the thread.

Principle

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.

Parameter

Feature

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.

Application

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.
