ST18*1.5 Metal Screw Sleeve,
anti seismic metal screw sleeve
Thread Sheath Manufacturer Wholesale Extended Screw Sleeve non-Standard Customization
The steel wire threaded sleeve is embedded into the threaded hole of low strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic, etc., which can form high-precision internal thread in accordance with international standards. It has the functions of high connection strength, anti-seismic, impact resistance and wear resistance, and can disperse the stress to protect the matrix thread, greatly prolong the service life of the matrix, and is widely used in electronic applications.
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.
