Professional Supply Flange Socket Head Cap Screw

This is a specially designed hex socket screw featuring a flange head that significantly increases the contact area. This not only enhances anti-loosening performance but also distributes the fastener’s pressure more effectively on the joint surface.

T&Y Hardware offers customers a wide range of flange Allen screws in various materials, specifications, and lengths, catering to both wholesale and retail needs. The company adopts a factory-direct supply model, strictly controls product quality, and provides customers with cost-effective procurement solutions.
