Drilled Industrial Steel Ball with Internal Threaded Holes M3-M6 Premium Connector

This is a specially processed industrial part, which refers to the tapping of internal threaded holes on the surface of a steel ball, intended for specific mechanical connections or assembly scenarios. Product form: Typically, it is a solid or through-hole steel ball (materials include carbon steel, stainless steel 304), with holes drilled on the ball and standard threads (such as M3, M4, M5, M6) tapped. Main Applications: Bolt Sphere Joints: In spatial truss structures, bolt spheres are spheres with multiple internal threaded holes, which connect multiple rods through high-strength bolts. They are widely used in large-span steel structures such as sports venues and terminal buildings. 10 Special Connectors: Used in situations where three-dimensional mechanical connections are required, such as customized brackets, sensor mounts, experimental devices, etc.
