ねじゲージを使用する際の力加減_「無理なく手でねじ込む」の解釈 | オーエスジー

Interpretation of the amount of force when using screw gauge _screwing by hand without strain

Regarding the use of screw gauge , JIS (JIS B 0251) describes how to screw it by hand without difficulty, but for example, if it becomes difficult or somehow passes through the thread screw plug gauge (GP), it cannot be said to be "unreasonable" and may not be able to make the correct judgment in the gauge inspection.

gauge is a precision measuring tool. Scratches such as chip burrs will damage the gauge , so please refrain from screwing it forcibly.
