As a type of threaded fastener, the pre installed internal thread of wire thread insert has obvious advantages compared to ordinary threads:
- Extending service life: Due to the stainless steel material of the steel wire thread insert, which has high hardness, the service life of softer base parts threads is increased by tens to hundreds of times; It increases its strength and avoids the occurrence of tripping and disorderly tripping.
- Enhanced threaded connection strength: applied to soft low strength alloy materials such as aluminum and magnesium, it can effectively enhance the connection strength of threads. The maximum tensile strength of ordinary internal threads in aluminum profiles is 1394N, while the minimum tensile strength of internal threads with pre installed wire thread insertcan reach 2100 N.
- Increasing the stress surface: can be used for thin body parts that require strong connections but cannot increase the diameter of screw holes.
- Improving connection conditions, increasing the bearing capacity and fatigue strength of threaded connections: As wire thread insertare elastic fasteners, the use of wire thread insertcan eliminate pitch and tooth profile deviations between screws and screw holes, distribute loads evenly, and thus improve the bearing capacity and fatigue strength of threaded connections.
- Rust proof: The characteristics of the steel wire thread insertmaterial itself and its extremely smooth surface make it suitable for use in harsh environments such as moisture and corrosion. It will not cause the matched substrate to rust and prevent the loss of expensive substrates due to the inability to disassemble threaded holes due to rust. Can be used in chemical, aviation, military equipment and other occasions that require high insurance factors.
- Wear resistance, heat resistance, and corrosion resistance: Due to the extremely high surface smoothness of the steel wire thread insert, it can effectively reduce the friction between the internal and external threads. The material itself has the characteristics of high temperature resistance and corrosion resistance. Can be used in frequently disassembled and installed components and frequently rotated screw holes to extend their service life.
- Anti seismic and anti loosening: The special structure of the locking type thread insertcan lock the screw in the screw hole in strong vibration and impact environments without loosening, and its locking performance is better than other locking devices. Can be used in instruments, precision and valuable power equipment, as well as aerospace, aviation, military equipment and other occasions that require high insurance factors.
- Easy to repair: In the event of threading errors or repairing damaged internal threads, the use of wire thread insertcan revive the substrate and allow the use of the original screws, which is both fast and economical. For example, diesel engine bodies, textile parts, various aluminum parts, lathe cutterheads, etc. may be scrapped due to damage to a screw hole. As long as they are re threaded and the thread insertis installed, the scrapped parts will come back to life.
- Conversion: Using wire thread insertto convert metric ←→ imperial ←→ international standard threaded holes is very convenient, fast, economical, and practical, suitable for any import or export product.
