锁紧型钢丝螺套 Helicoil Screw Locking Inserts

    Helicoil锁紧型钢丝螺套对螺栓有锁紧固定、防松脱的性能，用于防止螺栓在振动或冲击的环境中产生松动，Helicoil锁紧型钢丝螺套的中部分有一圈或是多圈多边型的锁紧圈，这些多边型的锁紧圈，就是用于加强螺栓螺钉锁紧功能用的。Helicoil锁紧型钢丝螺套可以进行多次的拆卸与安装，将其用于铸铁，合金钢，钛等产品的螺丝孔当中，也可以有效防止螺钉松动。Helicoil锁紧型钢丝螺套作为一种高强度的螺纹紧固件，可以对内螺纹孔的螺纹进行保护，防止螺纺受到损坏。尤其是在螺栓拆卸与安装时，防止螺丝孔螺纹磨损或捋丝滑牙等。Helicoil锁紧型钢丝螺套产品符合航空航天与军事标准（NASM8846 ， MA1565和MIL -N - 25027）。Helicoil锁紧型钢丝螺套受到广泛的测试，包括：拉力，扭力，剪切，抗振动和抗疲劳强度等。Helicoil品牌锁紧型钢丝螺套广泛应用于航空航天，电子，工业，汽车和军事部门等。

Helicoil Screw Locking Inserts
    HeliCoil Locking Insert provides an exclusive, resilient internal locking thread that grips the bolt and prevents it from loosening under vibration or impact. One or more coils of the HeliCoil insert, having a series of straight segments/ chords, achieve locking action. HeliCoil Locking Insert permits repeated assembly and disassembly and will not relax their grip on the screw even in tough metals such as cast iron, alloy steel, titanium, etc. HeliCoil Locking Insert positively secures threaded members against loosening caused by vibration and shock. HeliCoil Locking Insert has a high reusable factor permitting frequent removal and reassembly of bolt without appreciable loss of torque. It has positive self-locking torque, complying with NASM8846, MA1565 and MIL-N-25027. It eliminates the usage of lock wiring, lock nuts, lock washers, chemical compounds, plastic pellets/ patches and other locking mechanisms. The HeliCoil Locking Inserts are subjected to extensive tests in tension, torque, shear, vibration and fatigue, conducted by the American & European companies. Its applications include sectors like Aviation & Aerospace, Electronics, Industrial, Automotive and Military.
