Wire Thread Insert introduction

The wire thread insert is a new type of internal thread fastener. It is a spring-like internal and external thread concentric body precisely processed by high-strength, high-precision, smooth-surface cold-rolled diamond stainless steel wire. Mainly used to strengthen and protect internal threads of low-strength materials. The principle is to form an elastic connection between the screw and the thread in the base body to eliminate thread manufacturing errors and improve the connection strength.

 

Classification of steel wire inserts

The wire screw sleeve is divided into two types: ordinary type and locking type. The locking type is to add one or more locking rings on the basis of the ordinary type, which plays a role in tightening and preventing loosening of the assembly screws. Wire thread inserts are embedded in the threaded holes of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass steel, plastic, etc., which can form high-precision internal threads that meet international standards. They have high connection strength, shock resistance, impact resistance and wear resistance. Function, and can disperse stress to protect the base thread, greatly extend the life of the base.

Advantages and uses of wire thread inserts

1. Enhance connection strength and improve connection conditions. The steel wire insert is selected from low-strength materials such as aluminum and magnesium, which can avoid slipping wires and staggered teeth and obtain excellent connection performance.

2. Wear resistance. Used for frequently dismantled parts, can greatly increase the service life of the thread.

3. Increase the stress area. Used for parts that require strong connecting force but cannot increase the diameter of the screw hole.

4. Prevent loosening. Especially used in applications where high safety factors are required for products such as spacecraft.

5. Easy maintenance. Put the damaged screw hole into the wire screw sleeve, after repair, you can continue to use it to avoid the possibility of workpiece damage.

 

Because of these optimizations, wire thread inserts are widely used in civilian products such as rail and rail transportation, construction machinery, textile machinery, medical equipment, papermaking, weapons, radar, rockets, ships, steam turbines, and chemical industries. In foreign countries, it is not only used in aircraft, aerospace industry, but also in ships, automobiles, machine tools, motors, textile machinery and instrumentation industries. Even in light industrial products such as cameras, sewing machines, modular furniture, etc., such wire sleeves are widely used.
