5/16 x 1 1/4 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) is useful in equipment where accurate location and controlled movement depend on the shoulder rather than the thread. When installed in the proper assembly, the 5/16 x 1 1/4 shoulder can give the mating component a consistent shoulder surface for rotation, travel, or spacing. Typical uses for the 5/16 x 1 1/4 shoulder include production tooling, spacer positions, locating features, and compact mechanical assemblies. For the 5/16 x 1 1/4 size, 18-8 stainless steel gives equipment builders a general-purpose stainless option for shoulder locations exposed to moisture or handling, which can matter to machine builders. The 5/16 x 1 1/4 part is useful for both new builds and replacement work where shoulder-based location must be maintained. The 5/16 x 1 1/4 combination of socket drive access and shoulder geometry helps simplify installation, service, and replacement in compact machinery.
