1.范围
本标准适用于涂胶性能要求和确定外螺纹紧固件预涂胶的锁紧力,目的是识别和控制涂胶的关键材
料特性。

1.1材料。本标准包含两种等级的材料。除一般等级外,本标准规定了耐高温材料,这种材料保证在
200°C条件下能保证具有锁紧力,并符合一般要求。
1.1.1MaterialIdentification.ThesematerialsaredesignatedwiththefollowingGMnumbers:
GM6175M……Maxtemperature135°C
GM6194M……Maxtemperature200°C
1.1.1材料标识。材料标识用通用号表示:
GM6175M……最高温度135°C
GM6194M……最高温度200°C
1.2TypicalApplication.Thisspecificationisforexternallythreadedfastenersthatrequirea

Fastenerswiththesematerialsshallnotbereused.AthirdGMpreappliedthreadlocking
specification,GM6124M,isavailableforfastenersthatrequirelowerthreadlockingperformance.
1.2典型应用。预涂复胶层具有化学锁紧效果,可以预防因冲击和振动带来的松动。采用上述材料
的紧固件不能重复使用。通用预涂复螺纹锁紧标准,GM6124M,适用于要求偏低锁紧性能的紧固
件。
