Factory Supply Stainless Steel Locking Steel Wire Insert Protective Sleeve

Information

Wire thread insert made of high strength, high-precision, smooth surface of the cold-rolled stainless steel rod working diamond formed by the helical coil, a threaded hole embedded low-strength aluminum, magnesium alloy, iron, steel, glass, plastic and other materials of construction of the wire thread insert, The thread can be protected to prevent the screw hole from being damaged by vibration, impact, abrasion, rust and other problems, and greatly extend the service life of the substrate.

The difference between the locking wire thread insert and the ordinary wire thread insert is that a pentagonal or hexagonal ring (locking ring) of 1 to 2 turns is specially made in the middle of it.

When the bolt is screwed into the threaded hole formed by the locking wire thread insert, the bolt will receive resistance at the position of the locking ring. If the bolt continues to be screwed in forcefully, the polygonal side of the locking ring will bend elastically, and the elastic type will become close to Round, but there is always a tendency for the locking side to return to a straight side, so that the side of the locking ring clamps the bolt tightly to achieve the purpose of locking the bolt. When subjected to vibration and impact, the screws can be prevented from loosening and falling off, and the bolts can be disassembled repeatedly, which has better process performance than usual locking devices.

When the locking performance of the internal thread formed by the locking type wire thread insert decreases for a long time, the original thread insert can be removed, and a locking type wire thread insert is reinstalled, and the internal thread has a new look.

Principle

The locking wire thread insert is a new variety developed on the original basis of the ordinary wire thread insert. There are 1 to 2 turns of pentagonal or hexagonal shape in the middle of the locking type wire screw sleeve. When the bolt is screwed halfway into the threaded hole, the head of the bolt hits the locking ring. Some other conventional locking devices have superior locking performance and higher strength, and can be disassembled repeatedly.
When the screw is screwed into the screw hole of the locking wire thread insert, it is loose before entering the polygonal locking ring. When the screw enters the polygonal locking ring, the polygon needs to be opened to deform the locking edge. At this time, when the screw is screwed in, the frictional force given to the screw by the locking edge must be overcome. After the screw is tightened, this friction force can prevent the screw from loosening by itself, thus replacing other locking methods.
