Dia 6mm 6H Screw Lock Inserts DIN8140 Screw Locking Thread Inserts

Product Specification

M6 Stainless Steel 304 Screw Locking Thread Inserts High Strength For Repair

Information

Type wire locking nut and common type wire thread insert point is different from its middle portion with a special pentagonal ring having 1 to 2 or hexagonal ring (locking ring).
 

Type wire lock nut threaded fastener is a new, high-precision stainless steel wire is precisely machined rhombic cross section made of a spring-like member concentric with and external thread. Type wire lock nut to increase the turn or several turns in the locking ring on the basis of the ordinary type.

Type wire lock nut (Helicoil Free-Running Inserts) as compared with conventional steel wire thread insert wherein the polygonal portion having one or more loops of the locking ring, which can be screwed a screw, screwed in the screw thread A strong elastic force is generated on the upper part to ensure reliable locking and effectively avoid the loosening of the fastener due to vibration. Portion above the locking ring can be screwed into the screw by hand, after the necessary lock ring is screwed onto a screw to mechanically loaded. The locking wire thread insert has multiple disassembly and assembly without reducing the tightening torque of the thread.

Feature 

Screw Lock Thread Inserts besides have corresponding function normal Thread Inserts, also played the lock screw tight in the threaded hole, under vibration and impact, can make the screw does not fall off string, locking device process performance is good, than Free Running Thread Inserts has repeatedly disassembling and not reduce the screw torque, but also has the high usability. Its principle is in the middle of the thread, by one or more polygonal non-deformation ring to form a locking edge, the assembly screw to tighten the role of anti-loose.

1. The stainless steel thread has high strength.
2. The hardness of the screw surface can reach HRC43~50.
3. The surface accuracy can reach 2~4 μm.
4. Reduce the friction between the threaded surfaces. To
5. Increase the bearing capacity of the screws. To
6. Reduce the torque that the screw bears.
7. Make the load distribution on the entire rotating surface even.
8. Increase the load-carrying capacity of fasteners.

Parameter

Advantage

1. Wire thread inserts are used in various low-strength materials, which can greatly improve the wear resistance of screw connections and avoid damage to the connecting threads.

2. Due to the certain elasticity of the wire thread insert, the load distribution on each circle of the thread can be more uniform, eliminate the pitch and tooth form deviation between the screw and the screw hole, and can absorb vibration, thus improving the connection strength and resistance of the thread. Fatigue strength.

3. The locking wire thread insert can lock the screw in the threaded hole, so that the screw will not loosen when it is subjected to shock and vibration, and the process performance is better than that of the usual locking device.

4. Compared with the method of inserting steel or copper bushings, under the same strength conditions, screws with smaller size and higher strength can be selected, which can reduce the volume and reduce the weight.

5. The hardness of the wire thread insert is higher than that of the screw, so it is less worn during the assembly and disassembly process of the screw connection and can be used repeatedly. According to relevant experimental studies, the tensile strength of the wire thread insert is more than 7 times that of the screw, so the wire thread insert will not be damaged even if the screw is broken.

Application

It is widely used in aerospace components, locomotive, high-voltage electrical appliances, automotive power, wind power, nuclear power, communication and electrical industries. It is used in aluminum, magnesium, copper alloy, plastic, plexiglass, plywood, steel, cast steel and cast iron to make it more tough and firm
