所選用的扭力扳手的開口尺寸必須與螺栓或螺母的尺寸相符合，扳手開口過大易滑脫并損傷螺件的六角，在進口汽車維修中，應注意扳手公英制的選擇;各類扳手的選用原則，一般優先選用套筒扳手，其次為梅花扳手，再次為開口扳手，后選活動扳手。
The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. In the maintenance of imported vehicles, attention should be paid to the selection of the metric and English system of the wrench. Generally, the socket wrench is preferred, followed by the ring wrench, then the open wrench, and then the adjustable wrench.
(2)為防止扳手損壞和滑脫，應使拉力作用在開口較厚的一邊，這一點對受力較大的活動扳手尤其應該注意，以防開口出現字形，損壞螺母和扳手。
(2) In order to prevent the wrench from being damaged and slipping, the pulling force should be applied on the thicker side of the opening, which should be paid special attention to for the spanner with larger force, so as to prevent the shape of the opening from damaging the nut and wrench.
扭力扳手是按人手的力量來設計的，遇到較緊的螺紋件時，不能用錘擊打扳手;除套筒扳手外，其它扳手都不能套裝加力桿，以防損壞扳手或螺紋連接件
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 wrench, other spanners can not be equipped with a booster bar to prevent damage to the wrench or threaded connection parts
