Wire screw sleeve is a new type of internal threaded fasteners, wound from steel wire, with spring-type high-precision internal and external threaded concentric body. Its main features are as follows:

Enhancement and protection of internal threads: when the wire screw sleeve is embedded in the threaded holes of aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic and other low-strength engineering materials, it can form high-precision internal threads in line with international standards, effectively enhancing and protecting the internal threads of these materials.

High connection strength: the internal threads formed by the steel wire thread sleeve have high connection strength, which is anti-vibration, anti-impact and wear-resistant, and can disperse the stress to protect the base threads and prolong the service life of the base.

Wide range of applications: widely used in automotive, electronics, machinery, aerospace and other fields, suitable for threaded hole enhancement and repair of a variety of materials.

Easy to install and repair: During installation, the wire nut is pre-compressed by torque through the thread guide ring of the installation wrench, and after screwing in, it produces an expansion around the periphery and is firmly fixed in the threaded hole. When threading errors or repairing damaged threaded holes, it is economical and effective to use wire nuts as a means of repair.

Versatility and customization: Wire nuts are available in a wide range of types and materials, such as stainless steel, copper alloy, high-temperature alloys, etc., to meet the requirements of different environments and uses. Non-standard customized products are also available to meet specific needs.
