Torque wrench, also known as torque wrench and torque adjustable wrench, is a kind of wrench. According to the power source, it can be divided into electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench; The manual torque wrench can be divided into preset type, fixed value type, dial type, digital display type, sliding type, bending type, and kilogram wrench. When the tightness of screws and bolts is critical, the use of a torque wrench allows the operator to apply a specific torque value.
(1) The opening size of the selected torque wrench must be the same as that of the bolt or bolt
The size of the nut is consistent. The wrench opening is too large to slip off and damage the hexagon of the bolt. In the maintenance of imported vehicles, attention should be paid to the selection of metric and British wrench; The selection principle of all kinds of wrenches is generally to give priority to the simple wrench, followed by the ring wrench, the open wrench, and the adjustable wrench.
(2) In order to prevent the wrench from being damaged and slipping, the pull force should be applied to the thicker side of the opening, which should be paid special attention to the adjustable wrench with large stress, so as to prevent the "eight" shape of the opening from damaging the nut and wrench.
(3) The torque wrench is designed according to the strength of human hands. When encountering tight threaded parts, it is not allowed to hit the wrench with a hammer; Except for socket wrenches, other wrenches can not be equipped with an extension rod.
(4) When using the torque wrench, when you hear a "snap", this is the most appropriate time.
