Wire Thread Nserts:Use of steel wire insert

Increase connection strength:

It can be used in light and soft low strength alloy materials such as aluminum and magnesium, wood,

plastic, rubber and other deformable low strength materials, to avoid slipping, desserting and staggering

Wear resistance:

The utility model can be used in the machine parts which are frequently disassembled and installed and

the screw holes which are frequently rotated, so as to prolong the service life of the machine parts.

Common thread can be divided into coarse thread and fine thread, and there can be multiple pitches

for the same nominal diameter, among which the largest pitch is called coarse thread, and the rest are fine thread

How it works edit

The thread insert is made of high-quality stainless steel wire, with diamond cross-section and spring-shaped thread

by mechanical rolling. The diameter of the screw sleeve is larger than that of the screw hole.

When the screw sleeve is installed, it is compressed and tightened. After the installation, it will spring back to its original state,

so that the screw sleeve is permanently fixed in the screw hole. Because of its large diameter, the thread insert has a larger contact surface,

so it is stronger than the original thread.

To determine whether the thread is coarse or fine, first roughly determine the purpose of the lower thread.

If it is uncertain, then measure the length of N pitches with a caliper, divide by N, and then check the thread table

When the screw is screwed into the screw hole of the locking type steel wire sleeve,

it is loose before it

enters the polygon locking ring. When the screw enters the polygon locking ring,

it is necessary to open

the polygon to deform the locking edge. At this time, the screw needs to overcome

the friction force of the

locking edge on the screw. After the screw is tightened, this friction force can prevent

the screw from

loosening itself, thus replacing other locking methods.
