A: It is possible to break a hexagon wrench that has a side-to-side span of 2.5mm or less, by pulling on it too hard. B: With larger hexagon wrenches, by pulling on them manually as hard as you can, you will succeed in applying the required torque. (Please see the section on 10mm-span wrenches for further information)
翻訳についてのコメント
Literally: A: As for inadvertently breaking a hexagon wrench with human strength, they are of 2.5mm span sizes or less. B: When the size of the hexagon wrench gets larger, by applying the maximum amount of human strength, you may just manage to obtain the standard tightening torque. (Please consult the part about 10mm span hexagon wrenches.)
