Value Collection B10120 Shoulder Screw M10x1.50 12.9 Alloy Steel

Product Description

The VALUE COLLECTION B10120 is a metric shoulder screw engineered for precision mechanical assemblies where accurate shaft diameter and controlled axial positioning are required. The shoulder measures 12 mm in diameter and 30 mm in length, providing a smooth, ground bearing surface that serves as a pivot, guide pin, or spacer within a mechanism. The M10x1.50 threaded end anchors the screw into a tapped hole while the unthreaded shoulder carries load and maintains alignment. Manufactured from 12.9-grade alloy steel, this screw delivers high tensile strength suited to demanding industrial and mechanical applications. Installation requires a hex socket drive.

This shoulder screw is used in a wide range of industrial, tooling, and machine assembly applications where a precision-ground cylindrical surface is needed to locate or pivot a moving component. Typical uses include jigs and fixtures, linkage pivots, cam followers, and bearing locators in both light and heavy manufacturing environments. The uncoated finish is appropriate for applications where a post-install coating or lubrication is applied by the end user. Sold in packages of 10, making it suitable for maintenance stock and production builds alike.

Key Features

• 12 mm shoulder diameter and 30 mm shoulder length for precise fit and positioning
• M10x1.50 metric thread for secure fastening into standard tapped bores
• 12.9 alloy steel construction for high tensile and shear strength
• Hex socket drive for torque application in confined spaces
• Uncoated finish compatible with post-install coatings or lubricants
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards

Compatibility

Designed as an OEM-style or replacement shoulder screw for metric mechanical assemblies requiring a 12 mm shoulder diameter, 30 mm shoulder length, and M10x1.50 thread per ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 specifications.

Installation Notes

Shoulder screws of this type are installed by machinists, maintenance technicians, and mechanical assemblers using a hex socket driver sized to the head recess. Power down and de-energize any equipment before servicing fasteners in live machinery. Ensure the mating bore is clean and the thread is free of debris before installation. Do not substitute a shoulder screw for a standard cap screw where a precision shoulder diameter is functionally required.
