Alloy steel socket shoulder screws, commonly known as stripper bolts, with nylon insert combine a precision-machined shoulder with a factory-installed nylon locking element that provides prevailing torque during installation. The smooth shoulder serves as a bearing surface, guide, pivot, or spacer for moving components, while the threaded portion secures the assembly and the nylon insert helps resist thread loosening caused by vibration, repeated motion, and dynamic loading.
These fasteners are widely used in dies, tooling, fixtures, molds, automation equipment, robotics, conveyor systems, indexing mechanisms, rollers, guide assemblies, cams, linkages, packaging machinery, and OEM equipment where accurate positioning and controlled component movement are required. The internal hex drive allows installation in confined spaces while maintaining a compact assembly and providing convenient serviceability.
Manufactured from alloy steel, these socket shoulder screws are intended for demanding industrial mechanical applications. Proper fastener selection should consider shoulder diameter, shoulder length, thread size, threaded length, bearing requirements, mating-component tolerances, installation access, and operating conditions. The nylon insert provides prevailing torque but should not be considered a substitute for proper joint design or installation practices.
Cold Headers supplies alloy steel socket shoulder screws (stripper bolts) with nylon insert in a broad range of shoulder diameters, shoulder lengths, and thread sizes, including uncommon and difficult-to-source configurations. Individual product pages provide verified shoulder dimensions, thread specifications, head dimensions, hex socket size, and additional engineering information to support accurate product selection.
Begin by confirming the required shoulder diameter, shoulder length, and thread size. Review bearing requirements, mating-component tolerances, installation clearance, operating conditions, and the desired level of prevailing torque before selecting a fastener. Final selection should reflect the functional and mechanical requirements of the assembly.
Cold Headers Inc. has supplied specialty industrial socket fasteners since 1962.

Alloy steel socket shoulder bolts, commonly referred to as 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 cylindrical socket head allows installation where external wrench clearance is limited, making them well suited for compact mechanical assemblies requiring accurate alignment and controlled movement.
Manufactured from alloy steel, these socket shoulder bolts 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, thread size, threaded length, head diameter, head height, 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 bolt for each application.
Cold Headers supplies alloy steel socket shoulder bolts (stripper bolts) in a broad range of shoulder diameters, shoulder lengths, 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, 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.

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.

18-8 stainless steel shoulder bolts, commonly called stripper bolts, are precision fasteners featuring a smooth, accurately sized shoulder between the head and threaded section. The shoulder functions as a bearing surface, pivot point, guide, or spacer, allowing moving components to rotate or slide while the threaded portion secures the assembly. The internal hex drive permits installation where external wrench clearance is limited.
18-8 stainless steel is commonly selected for applications requiring general corrosion resistance in environments exposed to ordinary moisture, humidity, or routine washdown. Shoulder bolts are widely used in dies, fixtures, automation equipment, machinery, tooling, conveyor systems, guide mechanisms, pivot assemblies, rollers, cams, linkages, and other applications requiring controlled movement and accurate component positioning.
Unlike conventional cap screws, shoulder bolts are designed around the precision shoulder diameter and shoulder length rather than relying solely on the threaded section. Proper selection should consider shoulder diameter, shoulder length, thread size, threaded length, bearing requirements, mating-component tolerances, available installation access, and overall assembly design.
Cold Headers supplies 18-8 stainless steel shoulder bolts in a broad range of shoulder diameters, shoulder lengths, and thread sizes, including uncommon and difficult-to-source configurations.
