Alloy Steel Socket Head Shoulder Screws (Stripper Bolts) with Nylon Insert

Since 1962, Cold Headers has supplied precision Alloy Steel Socket Head Shoulder Screws (Stripper Bolts) with Nylon Insert to OEM manufacturers, industrial distributors, tooling specialists, maintenance professionals, and engineering teams throughout North America.

These precision shoulder screws combine a hardened alloy steel body with an integrated nylon insert to provide a secure, vibration-resistant assembly while maintaining the accurate bearing surface and positioning characteristics required in demanding industrial applications. Unlike standard socket head cap screws, the precision shoulder supports pivots, guides, spacers, stripper plates, fixtures, moving assemblies, and precision tooling where accurate alignment and repeatable motion are critical.

Description N/A 1/4 x 3/8 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is frequently selected where dies, fixtures, cams, or linkages require a shoulder surface for repeatable motion. Engineers use this style when ordinary clamping hardware would not provide the guide, pivot, spacer, or stop function required. Typical applications include press tooling, guided plate movement, stop blocks, and linkage assemblies. The insert feature gives buyers a nylon-insert shoulder screw option for applications where retention matters alongside guided movement. Tool and die shops often evaluate this family when stripper plate travel or fixture alignment depends on a consistent shoulder surface. As a stripper bolt, it can support tooling and guided-motion applications where the shoulder is part of the operating interface. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.

N/A 1/4 x 1/2 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert helps locate or guide moving parts in equipment where alignment and controlled travel are part of the design. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include industrial machinery, maintenance departments, equipment builders, and distributor sourcing. For maintenance teams, the nylon insert can help address loosening concerns in equipment subject to vibration or repeated motion. Purchasing managers get a clear shoulder-size callout for RFQ sourcing and replacement work. The design is useful when the fastener is part of the positioning system rather than only a threaded clamping point. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.

N/A 1/4 x 5/8 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert offers a practical solution when tooling or machine components need both socket-drive retention and a functional shoulder. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include dies, stripper plates, tooling nests, and fixture rebuilds. The nylon insert adds resistance to loosening in vibration-prone or movement-related assemblies without changing the basic shoulder function. Maintenance professionals may use this style when worn guide, stop, spacer, or pivot hardware needs a direct shoulder-size replacement. As a stripper bolt, it can support tooling and guided-motion applications where the shoulder is part of the operating interface. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.

N/A 1/4 x 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert helps locate or guide moving parts in equipment where alignment and controlled travel are part of the design. Unlike a standard socket head cap screw, the unthreaded shoulder is the working surface for bearing contact, location, or controlled travel. Typical applications include assembly equipment, pivoting components, locating nests, and serviceable machine designs. The nylon insert is useful in assemblies where a shoulder screw or stripper bolt must stay seated while nearby components move or cycle. Tool and die shops often evaluate this family when stripper plate travel or fixture alignment depends on a consistent shoulder surface. Alloy steel construction supports industrial fastening applications where the shoulder performs the working role in the assembly. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.

N/A 1/4 x 1 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert offers a practical solution when tooling or machine components need both socket-drive retention and a functional shoulder. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include OEM production equipment, replacement hardware, tooling support, and machine repair. The nylon insert supports resistance to loosening while the shoulder continues to provide the bearing, guide, spacer, or locating surface. Purchasing managers get a clear shoulder-size callout for RFQ sourcing and replacement work. The socket head shoulder screw format is well suited to serviceable machinery where access and repeatable location are both important. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
