How to test the performance of bolts? As a collectively owned research and testing institution, Baijian.com can conduct performance testing on high-strength bolts, anchor bolts, L-shaped bolts, T-shaped bolts, double headed bolts, fastening bolts, hexagonal bolts, torsion shear bolts, bridge connection bolts, ordinary bolts, large hexagonal bolts, and issue bolt performance testing reports. The testing cycle is short, and a bolt performance testing report can be issued within 7-15 days. The testing cost is low, the data is scientific and reliable, fair and rigorous, and it integrates testing, inspection, analysis, testing, technical consulting and other services, which can be used for testing the performance of bolts. Having the national high-tech enterprise certificate and CMA testing qualification certificate, with complete testing instruments, the testing report can be issued within 7-15 days Detection scope: high-strength bolts, anchor bolts, L-shaped bolts, T-shaped bolts, double headed bolts, fastening bolts, hexagonal bolts, torsion shear bolts, bridge connection bolts, ordinary bolts, large hexagonal bolts, etc Testing items: Mechanical performance testing, guaranteed load hardness, wedge load, anti slip coefficient, tensile load, tensile strength, metallographic analysis, torque coefficient, microstructure analysis, microhardness analysis, chemical analysis, chemical composition analysis, non-destructive testing (radiographic testing, magnetic particle testing, etc.), HIC stress testing, etc Testing standards
