AIR1551A - Torque Tightening Metric Screw Threaded Fasteners

Details
Document Number: AIR1551A
Revision Number: A
Title
Torque Tightening Metric Screw Threaded Fasteners
Scope
The purpose of this Aerospace Information Report (AIR) is to provide the aerospace propulsion industry with recommended assembly torque limits for threaded fasteners when a common torque value per fastener size is the objective. (The fasteners are based on the dimensional data in MA1518). It also provides a series of curves that show the effect of the coefficient of friction on the axial load produced in a fastener, when the recommended torques are applied.
