ThreadHigh precision Thread Gauge GO/NO GO Gage Metric Gauge 6H Precision Internal Screw Gage Fine,Pitch Thread Test Tooldetalles del producto > > >Features:Material: The measuring head adopts GR15 bearing steel and has strict heat treatment hardness of 58-65HRC. 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 matteand 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 process1. 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 Gauge==========High-concerned chemical : NoneDIY Supplies : MetalworkingType : Tap
