Metric alloy steel socket head shoulder screws, also known as metric stripper bolts, are precision fasteners manufactured with a accurately machined shoulder and an internal hex drive. The precision shoulder functions as a bearing surface, guide, pivot, spacer, or locating feature, while the threaded portion secures the assembly. Their metric thread sizes make them well suited for internationally designed machinery and equipment requiring accurate alignment and controlled movement.
Manufactured from alloy steel, these metric socket head shoulder screws are intended for demanding industrial mechanical applications. They are commonly specified for dies, molds, tooling, fixtures, automation equipment, robotics, conveyor systems, indexing mechanisms, guide assemblies, rollers, cams, linkages, packaging machinery, maintenance repairs, and OEM manufacturing where repeatable positioning and dependable performance are essential.
Proper fastener selection should consider shoulder diameter, shoulder length, metric thread size, threaded length, head diameter, head height, metric hex socket size, bearing requirements, mating-component tolerances, installation clearance, and service conditions. Individual product pages provide verified engineering dimensions to assist engineers and purchasing professionals in selecting the correct shoulder screw for each application.
Cold Headers supplies metric alloy steel socket head shoulder screws (stripper bolts) in a broad range of shoulder diameters, shoulder lengths, metric thread sizes, and body lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.
Begin by confirming the required shoulder diameter, shoulder length, metric thread size, and threaded length. Review bearing requirements, mating-component tolerances, installation clearance, operating conditions, and assembly requirements before selecting a fastener. Final selection should reflect the functional and mechanical requirements of the completed assembly.
