[0002] ‌A torque product is a tool used to measure and control torque, mainly providing an accurate torque value when tightening bolts or nuts.‌ Torque products are widely used in industries such as industrial and automotive maintenance, ensuring the reliability and safety of connections. High-strength bolt connections are a detachable connection method, and due to their advantages such as convenient construction, high construction efficiency, high strength, and low cost, they are widely used in industrial projects such as construction, energy, and vehicles. The tightening of high-strength bolts should be divided into initial tightening and final tightening to ensure that they exert their due mechanical properties. For torsion-shear high-strength bolts, when finally tightened, the removal of the plum blossom head is used as the tightening mark, which can better identify and review the final tightening effect. However, most of the review work requires secondary climbing operations, bringing great difficulties to sampling inspections.
