Metric Alloy Steel Socket Head Shoulder Screws (Stripper Bolts)

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.

Selecting the Correct Metric Socket Head Shoulder Screw

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.

Description	N/A M6 x 10 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is named by its 6 mm shoulder, not by its M5-0.8 threaded end. The shoulder rides in the assembly while the threaded end anchors below it, so both diameters must match the print. Stamping die sets and stripper plates use these metric stripper bolts as guided travel posts against springs. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution. Cold Headers has supplied specialty socket fasteners since 1962 and supports exact metric shoulder-screw identification. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Non-catalog shoulder diameters or shoulder lengths can be quoted when the standard range does not match the tool drawing. Inch-series Alloy Steel Socket Head Stripper Bolts are the related family when the print is not metric. Technical Highlights Style: Socket head shoulder screw (stripper bolt), internal hex drive Material: Alloy Steel Shoulder Diameter: 6 mm nominal (5.987 / 5.951 mm) Shoulder Length: 10 mm Thread: M5-0.8 (one size below the shoulder, per ISO 7379) Thread Length: 9.75 mm Head Diameter: 10.00 / 9.78 mm (max/min) Head Height: 4.50 / 4.32 mm (max/min) Hex Key Size: 3 mm Minimum Key Engagement: 2.4 mm Dimensional Standard: ISO 7379 Call 773-775-7900 or email Sales@coldheaders.com for pricing, availability, or a quote.	N/A M6 x 12 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is a metric alloy steel shoulder screw where the ground shoulder does the locating work. Order by the shoulder size and shoulder length; the smaller thread below the shoulder is intentional under ISO 7379 geometry. Mold slides, lifters, and guided tooling details use shoulder screws where the shoulder acts as the controlled sliding surface. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution. Cold Headers helps distributors, toolrooms, and maintenance teams keep shoulder diameter, length, and thread pairing aligned. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Alloy Steel Socket Head Stripper Bolts with Nylon Insert add a self-locking thread feature for vibration service.

N/A M6 x 16 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) functions as a precision pin that screws into place through a smaller M5-0.8 thread. The shoulder is ground slightly below nominal so it can slip into a reamed nominal bore and rotate or locate freely. Cam followers, rollers, and small wheels can run on the shoulder while the threaded end fixes the position. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution. For metric tooling repairs, Cold Headers can help quote the specified stripper bolt without converting it to an inch size. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. 18-8 Stainless Steel Socket Head Stripper Bolts are the stocked routing choice when the print specifies stainless material.

N/A M6 x 20 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) gives metric tooling one fastener with a retaining head, working shoulder, and anchoring thread. The head retains the part, the shoulder bears and locates, and the thread secures the fastener in the tapped hole. Metric linkage pivots use this style where the joint needs a smooth shoulder rather than threads through the moving member. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution. Cold Headers keeps metric shoulder screws separate from socket head cap screws so the locating function stays clear. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Alloy Steel Metric Socket Head Cap Screws are the clamping fastener choice when a metric print does not need a shoulder.

N/A M6 x 25 Alloy Steel Metric Socket Head Shoulder Screw (Stripper Bolt) is a socket head shoulder screw for die, mold, and machine motion built around a 6 mm shoulder. This is a locating and motion component, not a substitute for a clamp-load cap screw when the print calls for clamping. Guide posts on metric machinery use shoulder screws to align covers, slides, fixture details, and moving stops. Check shoulder diameter, shoulder length, thread size, thread length, socket size, and head dimensions before substitution. When the length or diameter is uncommon, Cold Headers can help review the metric shoulder screw requirement by exact size. ISO 7379 catalog nominals often list 6.5 mm here; this stocked 6 mm shoulder is the North American metric tooling variant. Cold Headers can review non-catalog metric shoulder lengths for repair work where the original equipment size is unusual.
