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.
ARP1928A has been reaffirmed to comply with the SAE five-year review policy.
