Precautions for testing high-strength bolts

      Many technical indicators for high-strength bolt testing require the use of high-strength bolt anti slip coefficient and high-strength bolt testing equipment, also known as high-strength bolt electronic axial force meter, to check. To test, it is necessary to first understand what testing items need to be tested and the relevant standards that need to be implemented. The testing method is only effective under the requirements of the relevant standards. The testing of high-strength bolts for large-scale wind power requires the detection of parameters such as torque coefficient, bolt load, bolt wedge load, nut load, bolt hardness, nut hardness, washer hardness, anti slip coefficient, and final tightening torque. The relevant standards implemented include "Code for Construction and Acceptance of Steel Structures" (GB 50205-2001), "Code for Manufacturing of Railway Steel Bridges" (TB10212-2012), and "Technical Conditions for High Strength Hexagonal Head Bolts, Hexagonal Nuts, and washers for Steel Structures" (GB/T1231-2006).
