5/16 x 1 1/2 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is selected for machinery where a precision shoulder provides bearing contact, location, or spacing in a serviceable joint. For repair or OEM use, the 5/16 x 1 1/2 shoulder helps serve as a locating shoulder in equipment where movement and spacing must remain consistent. The 5/16 x 1 1/2 configuration is relevant for material-handling mechanisms, spacer locations, and serviceable pivot points. Purchasing Departments may choose the 5/16 x 1 1/2 size because 18-8 stainless steel is often selected for shoulder screw locations where moisture resistance and general-purpose stainless performance are required. The 5/16 x 1 1/2 size is best matched to assemblies that need a defined shoulder for movement, spacing, or location. It can help keep OEM assemblies consistent when the 5/16 x 1 1/2 shoulder is part of the movement or spacing requirement.
