1/2 x 3 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) provides a stainless shoulder screw option for equipment that needs controlled motion and clean exposed hardware. For repair or OEM use, the 1/2 x 3 shoulder helps provide a bearing surface for guided or serviceable movement. The 1/2 x 3 configuration is relevant for clean machinery, food-equipment hardware where appropriate, and general industrial fixtures. Oem Equipment Builders may choose the 1/2 x 3 size because 18-8 stainless steel works well for many indoor and outdoor applications where moisture resistance and clean hardware are important. The internal hex socket on the 1/2 x 3 fastener gives installers a familiar drive style for assembly, adjustment, and replacement work. This 1/2 x 3 design supports tooling and fixture work where simple clamping would not provide the same functional bearing surface.
