ることを特徴とする有効ネジ長測定具。 The tip of the gauge holder is used as a reference abutting surface, and a vernier is carved on the partially cut edge surface approximately in the center of the holder, and a guide hole passing through the center is provided with a vernier on the tip. It is equipped with a thread gauge that screws into the threaded hole to be measured, and a gauge body with a main scale carved in the center of the shaft and a rotating part at the other end is inserted, and the reference contact surface and the top surface of the thread gauge, and The reference scales of the main scale of the gauge body and the vernier scale of the gauge holder match each other, and when the reference contact surface is applied to the threaded part to be measured and the rotating part is rotated, the threaded part is screwed together. An effective screw length measuring instrument characterized in that the gauge body is configured to move in the axial direction and the amount of movement can be directly read by a main scale and a vernier scale.
