Socket Shoulder Cap Screws (inch)

Socket shoulder cap screws are often called shoulder bolts or shoulder screws due to the key component that sets them apart from the socket product family- the shoulder. A socket shoulder screw has a raised cylindrical head that is often knurled, the same head design as found in socket head cap screws. Installation is completed the same too with a hexagon drive tool, such as a hex key. Directly below the bolt head is the key element, an unthreaded section or the shoulder. Lastly, a threaded shaft is found at the far end of the bolt.  Socket shoulder cap screws are most commonly utilized in mechanical applications that require a pivot point, guide pin, or extra spacing. The unthreaded shoulder allows for components to rotate around it yet maintain consistent connection in place.

• Black Oxide: Standard coating for socket products, offering a minimally protective layer on the bare steel. Beneficial for uniform color and reduced glare from the matte black appearance.
• Stainless-steel: Superior corrosion resistance with high durability.
