Socket Head Shoulder Screw

Socket Head Shoulder Screws are precision fasteners with an unthreaded shoulder used as shafts, pivots, or guides in mechanical assemblies. They are manufactured to ASTM, DIN, and ISO standards in alloy steel, stainless steel, carbon steel, or brass. The unthreaded shoulder provides accurate alignment and smooth bearing surfaces for moving components. Available in black oxide, zinc plated, stainless, and nickel finishes, they ensure durability, strength, and resistance to wear. They are widely used in tooling, dies, machinery, automotive components, and precision engineering applications.
