It is integrally formed and has high hardenability. The hexagonal shank is made of preferably solid steel, threaded structure, convenient link, and the surface is matte and non-slip.Accuracy: 6HThread gauge is a tool to measure the correctness of internal thread size. Thread gauge under 100mm is taper shank thread gauge. Thread gauge 100 mm above is double screw thread gauge. Easy to operate and maintain, supercor performance.Specification:Material: Bearing steelWeight: 14~221g/0.5~7.8ozInspection and measurement process 1. First, clean sheets and impurities must be cleaned before the thread gauge and the measured thread are positive, then the thumb and forefinger rotate the ring gauge, so that the thread in the free state can be determined according to the full length of the thread, otherwise it will not be able to determine. 2. After the use of the relevant inspection and metrological institutions inspection and metrology qualified, then the screw gauge and the measured thread pair after, use the thumb finger and the index finger rotation ring gauge, screw thread length within 2 pitch to be qualified, otherwise be judged to be non-conforming product.Package List:1* Thread GaugeNote:1. Before use: Thread gauge should be checked and qualified by relevant inspection and metrological institutions before being put into production site use. 2. Use: should pay attention to the test thread tolerance class and deviation code and thread gauge mark tolerance class, the deviation code is the same. 3. After the thread gauge is finished, clean and measure part of the attachment should be cleaned and stored in the specified quantity box. The production site should be placed in the position of the craft fixed position and light gently, so as to prevent the bump and damage the measuring surface. It is strictly forbidden to force screw threads into threads as cutting tools to avoid early wear and en-sure the accuracy of measuring tools. ==========High-concerned chemical : NoneDIY Supplies : Metalworking
