Description / Abstract:


The purpose of this aerospace recommended practice is to provide recommended torque values for attaching electrical devices to receiving members by means of screws, bolts, studs and nuts, i.e., standard mounting hardware

The values provided in the table cover selected steel, brass and aluminum materials used for standard mounting hardware. These values were based upon safe mechanical strengths as defined by general industry practices and existing aerospace requirements

These recommendations are general guidelines. Safety factors for any unusual mounting applications or operating conditions, such as vibration, impact, shear, and fatigue, should be given special consideration by the designer

The specified values are not intended to be design criteria for the minimum torque values that studs, posts, etc., should be able to withstand without failure

Also, these values are not intended to supersede those recommended by equipment manufactures or required by the equipment designer
