ActiveMechanical properties of fasteners--Widening test on nuts
紧固件机械性能 螺母扩孔试验
Application Summary AI generated
This standard specifies a test method to determine the mechanical properties of nuts by assessing their resistance to widening or splitting when a tapered mandrel is forced through the threaded hole. It is applied in the quality control and manufacturing of fasteners, particularly for nuts used in mechanical assemblies and structural connections. The test ensures that nuts meet specified strength and ductility requirements for safe and reliable performance under load.
