本规范规定了螺纹直径尺寸为0.1380至0.6250英寸的以下类型自锁螺母的要求: 一个 扳手螺母:即六角螺母、双六角螺母和花键螺母。 b 锚定螺母:即板形螺母、槽形螺母和柄形螺母。 板和组槽螺母的扳手螺母、柄螺母和螺母元件由耐腐蚀和耐热的镍基合金制成，其类型在统一编号系统下标识为UNS N07001，室温下的轴向拉伸强度为180,000 psi，在室温测试之前，零件的最大调节温度为1400°F。

This specification establishes the requirements for the following types of self-locking nuts in thread diameter sizes 0.1380 through 0.6250 inches: a Wrenching Nuts: i.e., hexagon, double hexagon and spline nuts. b Anchor Nuts: i.e., plate nuts, gang channel nuts, and shank nuts. The wrenching nuts, shank nuts, and nut elements of plate and gang channel nuts are made of a corrosion and heat resistant nickel-base alloy of the type identified under the Unified Numbering System as UNS N07001 and of 180,000 psi axial tensile strength at room temperature, with maximum conditioning of parts at 1400 °F prior to room temperature testing.
