How to judge the quality of M8 M10 M20 threaded rod？

To judge the quality of the welding rod, it can be evaluated from the following aspects: threaded bar size accuracy: Use calipers, micrometers, projectors and other instruments to measure the diameter, pitch, helix angle and other dimensional parameters of the lead screw to ensure that the dimensional accuracy meets the design requirements. threaded stud shape accuracy: Use straightness testers, roundness testers, cylindricity testers and other instruments to detect the shape parameters of the lead screw such as straightness, roundness, cylindricity, etc. to ensure the accuracy of its geometric shape. galvanized threaded rod surface quality: Use roughness testers, hardness testers, wear testers and other instruments to detect the surface quality parameters such as roughness, hardness, wear resistance of the lead screw surface to ensure its surface quality and durability. threaded rod anchor mechanical properties: Use universal testing machines, tensile testing machines and other instruments to test the tensile strength, yield strength, elongation and other mechanical performance parameters of the lead screw to ensure that its mechanical properties meet the use requirements. threaded steel rod accuracy grade: According to the accuracy grade standard of the lead screw, use the accuracy grade tester to test and evaluate the accuracy of the lead screw to ensure that its accuracy grade meets the design requirements. Through the comprehensive evaluation of the above methods, the quality of the screw can be judged more comprehensively to ensure that it can work stably and reliably during use.
