1/2 x 2 1/4 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. In a 1/2 x 2 1/4 shoulder application, the working surface can maintain alignment in assemblies that move, index, or return to the same location. Equipment builders may use the 1/2 x 2 1/4 size in material-handling mechanisms, spacer locations, and serviceable pivot points. The 1/2 x 2 1/4 product also gives machine builders a material choice where 18-8 stainless steel offers general-purpose corrosion resistance, a clean appearance, and useful moisture resistance in many industrial environments. Selection should be based on the 1/2 x 2 1/4 shoulder size, material, and machine function required by the assembly. The 1/2 x 2 1/4 combination of socket drive access and shoulder geometry helps simplify installation, service, and replacement in compact machinery.
