This standard provides definitions and guidelines for torque application of fasteners with threaded connections. It specifies the procedures and parameters necessary to ensure proper tightening of bolts, screws, and nuts in various applications. The document covers aspects such as torque wrench calibration, lubrication impact on torque requirements, and methods for achieving consistent preload in assemblies. It aims to prevent over-tightening or under-tightening that could lead to mechanical failure or damage.
