1/2 x 1 1/4 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) provides a defined shoulder for controlled movement in tooling, fixtures, automation equipment, and OEM machinery. For repair or OEM use, the 1/2 x 1 1/4 shoulder helps combine fastening with a functional shoulder used for position and motion control. The 1/2 x 1 1/4 configuration is relevant for fixture repair, automation equipment, guided components, and replacement shoulder hardware. Maintenance Teams may choose the 1/2 x 1 1/4 size because the stainless material supports general-purpose corrosion resistance for fixtures, automation equipment, and OEM machinery exposed to moisture. For OEM work, the 1/2 x 1 1/4 shoulder provides a clear locating surface while the socket head remains accessible. The 1/2 x 1 1/4 combination of socket drive access and shoulder geometry helps simplify installation, service, and replacement in compact machinery.
