Thread inspection tools - — Screw thread gauge is introduced

Thread gauge in the thread inspection of bimetallic thermometer are common, thread gauge, also known as the thread check gauge, thread gauge, is often used to test for determining thread size is correct. Thread sizes is made up of thread diameter and pitch. Usually when choosing thread gauge test thread specification, you know. Thread gauge inside and outside according to the test is divided into plug gauges and thread ring gauge, there is also a flake tooth type gauge. Thread plug gauge is a tool for measuring the correctness of the internal thread size. Thread ring gauge is used to measure the correctness of the external thread size, according to the screw thread standard is different, some is 1 piece, some for 2 pieces. Thread plug gauge and the ring gauge is generally used in manufacturing, easy to control the quality. Tooth type gauge generally used in the production, a set of teeth tooth shape rules including commonly used 0. 5/0. 6/0. 7/0. 75/0. 8/0. 9/1. 0/1. 25/1. 5/1. 75/27, tooth gauge can confirm agreement with tooth type unknown thread tooth pitch.
