Thread Repair M3 304SS Thread Inserts Screw Lock For Gearbox

Information

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.

Parameter

Advantage

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.

Application

1. Quickly and effectively repair damaged threads on a variety of materials.

2. Enhance the thread strength on light materials, such as large and medium-sized non-ferrous metal castings, die castings and ductile ferrous metal base materials, as screw holes that are often screwed in and out.

3. It is especially suitable for use in environments requiring high-strength internal threads, with strong seismic and pull-out resistance. It has higher strength than commonly used wire thread inserts, and is firmly connected to the base body, and will not be separated from the base body even when working under shock or vibration environment.

4. Remedy the wrong hole and avoid reprocessing the wrong part.
