Value Collection 537088PR Shoulder Screw M5x0.8 Alloy Steel

Product Description

The VALUE COLLECTION 537088PR is an alloy steel shoulder screw with an M5x0.8 metric thread and a 6 mm shoulder diameter. The shoulder measures 40 mm in length, providing a precise bearing surface for rotating or sliding components such as linkages, pivot points, and guided assemblies. The hex socket drive allows installation with a standard hex key in confined spaces. Built to material grade 12.9, the fastener delivers high tensile strength suited for demanding mechanical and industrial applications. The uncoated finish is standard for bare alloy steel and is compatible with most post-installation coating or plating processes.

This shoulder screw is used in mechanical assemblies where a controlled-diameter shank is required to act as a pivot, spacer, or guide pin. Typical applications include fixture building, tooling, jig construction, machine frames, and precision linkage assemblies. The metric M5x0.8 thread and 6 mm shoulder make it a common selection for light-to-medium load pivot joints in both production and maintenance environments. Machinists, tool-and-die makers, maintenance technicians, and assembly mechanics are the primary installers of this fastener type.

Key Features

• 6 mm shoulder diameter with 40 mm shoulder length for precise bearing and pivot applications
• M5x0.8 metric thread conforms to ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards
• Material grade 12.9 alloy steel for high tensile and proof load capacity
• Hex socket drive for installation in restricted clearance areas using a standard hex key
• Uncoated finish suitable for secondary plating or use as-supplied in dry or lightly lubricated assemblies
• Head diameter range of 9.78 to 10 mm with head height of 4.32 to 4.50 mm

Compatibility

Designed as a standard metric shoulder screw for mechanical assemblies requiring an M5x0.8 threaded fastener with a 6 mm precision shoulder, conforming to ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 dimensional standards.

Installation Notes

Installation requires a properly sized hex key or Allen driver matched to the socket head. Ensure the mating bore is dimensioned to the 6 mm shoulder diameter for correct fit and function. Do not overtighten into tapped holes, as grade 12.9 fasteners used in soft materials may strip the receiving thread. Thread engagement depth should conform to applicable engineering standards for the mating material.
