Steel Screw Sleeve Without Mounting Handle , Tangless Wire Inserts


"Tailless screw sleeve" is also called "steel screw sleeve without mounting handle", which is a kind of wire screw sleeve (threaded wire sleeve).

No mounting shank wire thread has a similar slot in the hook-shaped ends, when the end of the collar without the installation, the use of special installation tools, no need to distinguish the direction of the collar, can be installed directly, it is The tail screw sleeve is incomparable, which greatly improves the work efficiency. Since no tail and no mounting shank nut, thus eliminating the step of removing the mounting shank, to further improve work efficiency, and completely avoid the problems caused due to mounting shank removal.

The difference between tailless screw sleeve and tail screw sleeve

◆ Difference 1:
The installation of the tailless screw sleeve is relatively simple, non-directional, and convenient to install, eliminating the cumbersome links of removing the installation handle of the ordinary tailed wire screw sleeve.
Save time and improve efficiency!

◆Difference 2:
The installation of the tailless screw sleeve is extremely convenient without the trouble of removing the tail handle. After the installation of the ordinary tail wire threaded sleeve is completed, the installation handle needs to be broken. After the tail is removed, it is not easy to clean up, which is easy to cause retention, and in serious cases, it will affect the quality of the entire product.

◆Difference 3:
There are complete installation tools for tailless wire thread inserts, including pneumatic tools, electric tools, and supporting tool brackets for batch installation, which are suitable for mass installation and use, and are very helpful to improve work efficiency!


The tailless screw sleeve is a new type of threaded sheath product developed on the basis of the ordinary threaded sheath. The tailless screw sleeve overcomes the shortcomings of the traditional threaded sheath mounting handle and the low installation efficiency. The traditional threaded sheath mounting handle cannot be slotted. The control is precise, resulting in the phenomenon that the tail is not easy to break or is too easy to break. When removing the handle, the tail is easy to protrude, which affects the screwing of the thread and seriously affects the quality of the product. .
At the same time, the traditional steel wire thread insert seriously affects the production efficiency when installing and removing the handle, and the installation is slow. The tailless screw sleeve adopts a threaded rotary hook type installation tool, which fully considers the efficiency of the installation, and the installation does not need to remove the handle and has no directionality.

1. It can form high-strength, wear-resistant, high-precision, interchangeable standard internal threads on mechanical parts made of metal or non-metal materials (such as aluminum, magnesium and other light alloy engineering materials). Parts, cast steel, and cast iron can improve the durability of the screws, and can prevent the screws from loosening and falling off and fatigue fracture caused by various vibrations.

Typical applications: high-voltage switchgear, hydraulic machinery, welding equipment, tobacco machinery, microwave communications, auto parts, air separation equipment, coal machines, power machinery, textile and chemical fiber machinery and furniture, etc.

2. When repairing wrongly processed or damaged internal threads, wire thread inserts (threaded sheaths) can be used as a repair method, which can be quickly and effectively repaired without increasing the weight and volume of the original product, and at the same time Can meet or exceed the original technical requirements.

Typical application: Repair of threaded holes of various parts after tripping, such as: repair of threaded holes of injection molding machine template. Repair of threaded holes in engine cylinders, etc.

3. It is very convenient and fast to use steel wire threaded sleeve (thread sheath) to convert between metric and inch.
