Anti - Loose 304SS Thread Inserts Screw Locking MS21209 Radiator
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, protection can be threaded, screw holes are prevented from vibration, shock, wear, corrosion and other damage problems, greatly extend the life of the matrix.
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
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.
