【50-piece removable thread checker kit】 The nut and bolt thread checker kit contains 27 standard sizes and 23 metric sizes, of which blue is imperial and red is metric. Each thread checker is protected by the corresponding position in the sponge in the box to ensure precision. 【Three ways to read]】 Another highlight of this screw gauge is that you can read the size clearly and conveniently in three ways: the size engraved on the gauge bar, the size chart on the coated paper sticker, and the size screen-printed on the foam.
