Standard for thread sheath

2024-10-29

Thread sheath, also known as wire screw sleeve or braces, is the use of its spring tension characteristics, the screw set into the female thread, so that the torque/tension load of the thread bite is balanced, so that the strength of the entire thread can be enhanced to achieve a better locking effect.

Use of wire screw sleeve: In the machining process of the workpiece, some of the more software materials such as aluminum, copper, cast iron, and even bakelic and plastic, in the processing of the workpiece thread parts, due to its own material is not hard enough, so it will cause the lock screw slip, and the thread sheath (wire screw sleeve) can solve this problem, you can reexpand the damaged thread hole and tap the tooth, the screw set into it. It forms a new, stronger internal thread. Of course, we do not have to wait until the thread is broken and then do the remedial action, in fact, we can drill and tap teeth according to the size of the thread sheath at the beginning and load the wire screw sleeve, which improves the product quality and effectively avoid future losses.

Thread sheath/steel wire sheath applicable industry: many industries are its applicable object, such as the automotive industry, hardware products, aluminum products, copper products, etc., but meet the following three conditions of the environment is more suitable:

1, the workpiece needs to be machined with internal threads

2, the work itself is soft or not strong enough

3, the internal thread needs to be installed screws or even need to be removed back and forth

Material of screw sleeve

Screw sleeve generally used material: Steel screw sleeve/thread sheath generally uses high-quality SUS304 stainless steel as raw materials, processed into a precision diamond section with cold binding, and then bent, machined, processed into a spiral screw sleeve according to the corresponding specifications, and then aged treatment, so that its metal mechanical stability and fatigue resistance, the general hardness of HRC40 or more, Therefore, the work after using the screw sleeve is more durable than the work without use, and even more than the workpiece after heat treatment.
