Adhesives — Determination of torque strength of anaerobic adhesives on threaded fasteners

The test method described is used to make comparative assessments of the securing or locking effect of anaerobic adhesives. It may be used for other types of adhesives. Its principle is determining the torque required to unscrew a bonded nut and bolt assembly, including the initial torque required to break the bond, and the torque measured after turning the nut 180°.
