3/8 x 1/8 18-8 Stainless Steel Socket Head Shoulder Screw (Stripper Bolt) helps solve motion-control and location challenges where the shoulder is the working surface of the fastener. For repair or OEM use, the 3/8 x 1/8 shoulder helps help a guided part move predictably against a defined shoulder surface. The 3/8 x 1/8 configuration is relevant for cleanroom-adjacent equipment, service fixtures, alignment stops, and guided machine details. Machine Builders may choose the 3/8 x 1/8 size because 18-8 stainless steel is a practical choice where corrosion resistance and a clean finished look matter on exposed or serviced hardware. Specify the 3/8 x 1/8 Socket Head Shoulder Screw when the shoulder function is central to the assembly design. The 3/8 x 1/8 combination of socket drive access and shoulder geometry helps simplify installation, service, and replacement in compact machinery.
