6H Tolerance Thread Gage Hex Handle Metric Thread Gauge Double End Thread Gauge Measurement Tool

Label:Yes Easy to operate and maintain, supercor performance. Factory New and Premium grade. Thread plug gauge under 100mm(3.94in) is taper shank thread plug gauge. Thread plug gauge 100mm(3.94in) above is double screw thread plug gauge. Thread plug gauge is a tool to measure the correctness of internal thread size.

Specification: Material: Bearing steel Inspection and measurement process 1. First, clean sheets and impurities must be cleaned before the thread plug gauge and the measured thread are positive, then the thumb and forefinger rotate the ring gauge, so that the thread in the 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 plug 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. Color: Silver + Black Size: 9.2 cm(3.62 in) Package List: 1* Thread Plug Gauge

Note: 1. Before use: Thread plug 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 plug gauge mark tolerance class, the deviation code is the same. 3. After the thread plug 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 ensure the accuracy of measuring tools.
