Stainless Steel Non Standard Fastener Wire Thread Insert Custom Size Helicoils

Stainless Steel Non - Standard Fastener Wire Thread Insert Custom Size Helicoils

Information

There are two styles of wire thread insert tanged screw thread inserts. The standard or “Free-Running” tanged insert provides a smooth free-running thread, while the “Screw-Locking” tanged insert provides self-locking torque on the male member by a series of “chords” on one or more of the insert coils.

Free-Running tanged screw thread inserts are greater in diameter than the tapped hole into which they are installed. In the assembly operation, the torque applied to the tang reduces the diameter of the leading coil and permits it to enter the tapped thread. When the torque or rotation is stopped, the coils expand with a spring-like action, anchoring the insert permanently in place against the tapped hole.

Screw-Locking tanged screw thread inserts provide an exclusive, resilient internal locking thread that grips the bolt and prevents it from loosening under vibration or impact. Screw-lock inserts permit repeated assembly and disassembly yet will not relax their grip on the screw even in tough metals such as cast iron, alloy steel, titanium, etc.

Material classification

A. Cr-Ni stainless steel material: through the combination of strength and material, it is used under normal circumstances, and is used under mild structure, aluminum alloy structure, sea water, chlorine-containing liquid, and increased corrosion resistance.

B. Copper alloy material: used when copper is required or when the threaded connection is frequently adjusted; used when it is required to be used for electrical conductivity or self-lubricating.

C. High-temperature alloy materials: heat-resistant use when the temperature is 500-750℃; for aerospace assembly technology, aircraft engines, and internal combustion engine turbo compressors when operating within 750℃.

Advantage

1. Increase the bearing surface. It is used for parts that require a strong connection force and cannot increase the diameter of the screw hole.

2. Anti-loosening. It is especially used in occasions where products such as spacecraft require a high insurance factor.

3. Easy to maintain. Install the damaged screw hole into the steel wire screw sleeve and continue to use it after repairing to avoid the possibility of damage to the work piece.
