Value Collection 537120PS Shoulder Screw M6x1 Alloy Steel

Product Description

The VALUE COLLECTION 537120PS is a metric shoulder screw designed for precision mechanical assemblies requiring a hardened, close-tolerance pivot or spacer point. Built from alloy steel at material grade 12.9, this fastener delivers high tensile strength suited to demanding industrial and mechanical applications. The 8mm shoulder diameter and 40mm shoulder length provide a precise bearing surface, while the M6x1 threaded end secures the screw in the mating component. Drive engagement is via a hex socket, allowing installation with standard hex key tooling. The screw ships uncoated and meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards. Installation requires ordering in multiples of 10.

This shoulder screw is used in fixtures, jigs, linkage assemblies, robotic mechanisms, and general industrial machinery where a smooth, hardened shoulder must rotate, slide, or pivot against a mating bore. The 8mm shoulder mates with standard 8mm bore components. Typical installers include mechanical assemblers, maintenance technicians, and machine builders working with metric-standard hardware across both light and heavy industrial settings. The grade 12.9 alloy steel construction makes it appropriate for high-load pivot applications where softer or lower-grade fasteners would fail prematurely.

Key Features

• 8mm shoulder diameter and 40mm shoulder length for precise bearing surface engagement
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Hex socket drive compatible with standard metric hex keys
• M6x1 metric thread for secure fastening in metric-tapped components
• Uncoated finish suitable for applications where coating buildup on the shoulder would affect fit
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards

Compatibility

Designed as a metric shoulder screw replacement or new-installation fastener for any assembly requiring an 8mm shoulder diameter and M6x1 thread engagement in conformance with ASME/ANSI B18.3.3.M, BS 4168, or ISO 7379 specifications.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a metric hex key sized to the socket drive. Ensure the mating bore is clean and dimensionally correct for an 8mm shoulder before installation. Apply appropriate thread-locking compound or torque per the assembly drawing requirements for the specific application. Do not exceed the design load for the grade 12.9 rating of this fastener.
