Self-lock wire thread inserts are a type of high-strength fastener with internal and external threads. Among them, the locking-type wire threaded insert can securely lock the screw in the threaded hole, preventing it from loosening when subjected to impact and vibration. Compared to typical locking devices, the locking-type wire threaded insert exhibits superior performance in terms of craftsmanship.
The special construction of the locking-type threaded insert allows it to firmly secure the screw in the threaded hole, preventing it from loosening in environments with intense vibration and impact. This performance makes the locking-type threaded insert suitable for applications requiring a high safety factor, such as instruments, precision and valuable power equipment, as well as aerospace, aviation, military equipment, and other high-demand scenarios.
When a screw is threaded into the hole formed by the locking-type threaded insert, the screw encounters resistance at the position of the locking ring. Continued force applied to tighten the bolt causes the edges of the locking ring’s polygonal shape to undergo elastic bending, approaching a circular shape. However, the locking edge always tends to return to a straight edge, effectively gripping the bolt and achieving the purpose of locking it. In the presence of vibration and impact, the locking-type threaded insert prevents the screw from loosening and falling out, and the screw can be repeatedly disassembled, demonstrating better craftsmanship performance than typical locking devices.
