1. Extended service life: Because wire thread inserts are made of stainless steel, they have high hardness, increasing the service life of softer base thread by tens to hundreds of times; increasing their strength and preventing stripping and cross-threading.
2. Enhanced threaded connection strength: Applied to soft, low-strength alloy materials such as aluminum and magnesium, they can effectively enhance the connection strength of threads. The maximum tensile strength of ordinary internal threads on aluminum profiles is 1394 N, while the minimum tensile strength of internal threads pre-installed with wire thread inserts can reach 2100 N. [2] 3. Increased load-bearing surface: They can be used for thin-body parts that require strong connections but cannot increase the diameter of the threaded hole.
4. Improved connection conditions, increased load-bearing capacity and fatigue resistance of threaded connections: Because wire thread inserts are elastic fasteners, using wire thread inserts can eliminate pitch and tooth profile deviations between the screw and the threaded hole, making the load evenly distributed, thereby improving the load-bearing capacity and fatigue resistance of threaded connections.
5. Rust Prevention: The inherent properties of the wire thread insert material and its extremely smooth surface prevent the mating base material from rusting and seizing up in harsh environments such as humidity and corrosion. This avoids the loss of expensive base material replacement due to the inability to disassemble the threaded hole because of rust. It can be used in chemical, aerospace, and military equipment where a high safety factor is required.
6. Wear Resistance, Heat Resistance, and Corrosion Resistance: Due to the extremely high surface smoothness of the wire thread insert, it effectively reduces the friction between the internal and external threads. The material itself also possesses high temperature resistance and corrosion resistance. It can be used in machine parts that are frequently disassembled and installed, and in frequently rotated threaded holes, extending their service life.
7. Vibration Resistance and Loosening Prevention: The special structure of the locking type insert can lock the screw in the threaded hole in strong vibration and impact environments, preventing it from loosening. Its locking performance is superior to other locking devices. It can be used in instruments, precision and valuable power equipment, and aerospace, aviation, and military equipment where a high safety factor is required.
8. Facilitates Maintenance: When thread machining errors occur or damaged internal threads need repair, using wire thread inserts can revive the base material, allowing the original screws to be used, which is both quick and economical. For example, diesel engine blocks, textile components, various aluminum machine parts, lathe tool holders, etc., may be scrapped due to a damaged threaded hole. Simply re-tapping the hole and installing a thread insert can revive the scrapped part.
