Value Collection 537218PR Shoulder Screw M10x1.5 Alloy Steel

Product Description

The VALUE COLLECTION 537218PR is a metric shoulder screw designed for precision fastening applications requiring a controlled-diameter shank. The shoulder measures 12 millimeters in diameter and 90 millimeters in length, providing an accurate bearing or pivot surface in mechanical assemblies. The M10x1.5 threaded end secures the fastener in tapped holes, while the hex socket drive allows installation with standard Allen keys or hex bit drivers. Manufactured from alloy steel at material grade 12.9, this screw delivers high tensile and proof-load strength suited to demanding industrial and mechanical engineering applications. The uncoated finish leaves the base alloy steel exposed.

Shoulder screws of this type are used in jigs, fixtures, die sets, and machine assemblies where a precision-ground shank acts as a bearing pin, pivot, or guide. The 12-millimeter shoulder diameter and 90-millimeter shoulder length make this screw appropriate for medium-to-heavy-duty fixture work and applications requiring extended pivot travel. Installation is performed by machinists, toolmakers, and mechanical assembly technicians across manufacturing and industrial maintenance environments.

Key Features

• Grade 12.9 alloy steel construction for high tensile strength in demanding fastening applications
• 12-millimeter shoulder diameter with a 90-millimeter shoulder length for an extended precision bearing surface
• M10x1.5 metric thread for secure engagement in standard metric tapped holes
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Uncoated finish; head diameter ranges from 17.73 to 18 millimeters and head height from 8.78 to 9 millimeters
• Meets ASME/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 standards

Compatibility

Designed as a metric shoulder screw replacement or original installation fastener for jigs, fixtures, die sets, and mechanical assemblies requiring an M10x1.5 thread and a 12-millimeter shoulder diameter.

Installation Notes

Install using a hex key or hex socket bit sized to the socket head; ensure the receiving tapped hole is clean and free of debris before threading. Power down and de-energize any machinery before servicing fasteners in live equipment. Grade 12.9 fasteners should not be welded or heat-treated in the field, as this degrades their mechanical properties. Follow applicable machine-design standards and torque guidelines from the relevant ASME or ISO standard for the assembly.
