Value Collection 537306BR Shoulder Screw M16x2 Alloy Steel

Product Description

The VALUE COLLECTION 537306BR is a metric shoulder screw designed for precision fastening applications requiring a hardened, close-tolerance shoulder. The screw features a 20 mm shoulder diameter and a 90 mm shoulder length, making it well-suited for use as a pivot point, spacer, or guide in jigs, fixtures, and mechanical assemblies. Driven by a hex socket, it accepts a standard Allen key or hex bit. Manufactured from alloy steel to material grade 12.9, it delivers high tensile strength and resistance to fatigue loading. The uncoated finish leaves the steel surface bare for applications where post-installation coatings or close-dimensional tolerances are required.

This shoulder screw is used across industrial maintenance, tooling, and machine assembly applications. It is appropriate for fixtures, die sets, linkages, and pivot mechanisms where a precision cylindrical shoulder must locate or guide a mating component. The M16x2 metric thread engages standard metric tapped holes. Licensed trades and MRO technicians working in manufacturing, millwright, and mechanical maintenance environments are the typical installers. It is sold individually and packaged as a single unit.

Key Features

• 20 mm shoulder diameter with 90 mm shoulder length for precision location and guiding
• M16x2 metric thread for engagement in standard metric tapped bores
• Grade 12.9 alloy steel construction for high tensile and fatigue strength
• Hex socket drive compatible with standard Allen keys and hex bit drivers
• Uncoated finish maintains tight dimensional tolerances as supplied
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards

Compatibility

Designed as a standard metric shoulder screw for use in fixtures, jigs, die sets, and mechanical assemblies requiring an M16x2 threaded fastener with a 20 mm precision shoulder.

Installation Notes

Installation is performed by millwrights, tool and die technicians, or mechanical maintenance professionals. Ensure the mating tapped hole is clean and free of debris before engagement. Use a calibrated hex key or torque-limiting driver appropriate for grade 12.9 fasteners and follow applicable fastener torque guidelines for the assembly. Do not use impact drivers on socket shoulder screws without verifying torque control.
