Bolt Tensile/Wedge Load Nut Guaranteed Load Testing Machine

Fastener mechanical tests are usually bolt and nut tests.The bolt test includes the bolt tensile fracture (or load holding) test and the wedge load test; the nut is usually the nut load holding test (tension or compression load holding).The bolt/nut tensile testing machine is mainly suitable for testing the mechanical properties of bolts, nuts, standard parts, and fasteners. It can accurately detect the tensile strength and yield strength of bolts, standard parts, and fasteners; the maximum load-bearing capacity value of screw threads, nuts, and screws, and the maximum deformation of the screw when damaged. The test meets the GB/T228-2021 test methods and standards.It is suitable for testing the mechanical properties of bolts, nuts, standard parts and fasteners. It can accurately detect the tensile strength and yield strength of bolts, standard parts and fasteners, the tensile strength of bolts, wedge load and the guarantee load test of nuts.
