Value Collection 537112PS Shoulder Screw M6x1 Alloy Steel

Product Description

The VALUE COLLECTION 537112PS is an alloy steel shoulder screw with a hex socket drive, designed for precision fastening applications requiring a smooth cylindrical shoulder as a bearing or pivot surface. The shoulder measures 8 millimeters in diameter and 20 millimeters in length, with an M6x1 metric thread. Built to material grade 12.9, this screw delivers high tensile strength suited for demanding mechanical assemblies. The uncoated finish is compatible with a wide range of standard installations. Weighing approximately 0.01 pounds, it is a compact fastener appropriate for machine builders, maintenance technicians, and mechanical assemblers working with metric fastener systems.

This shoulder screw is used in applications where a precise shoulder diameter is needed to align, locate, or provide a rotating pivot point within a mechanical assembly. Typical uses include jigs and fixtures, die sets, linkage assemblies, and equipment requiring controlled shear load transfer. The M6x1 thread standard makes it a direct fit for metric-threaded components in industrial machinery, automated equipment, and precision mechanical devices. Sold individually with a minimum order quantity of 10 units.

Key Features

• 8 millimeter shoulder diameter provides a precise bearing or pivot surface
• 20 millimeter shoulder length for consistent alignment depth
• M6x1 metric thread for compatibility with standard metric hardware
• Grade 12.9 alloy steel construction for high tensile and shear strength
• Hex socket drive for torque application in confined spaces
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 standards

Compatibility

Designed as a metric shoulder screw conforming to ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379, suitable for use in any application requiring an 8 millimeter shoulder diameter with an M6x1 thread.

Installation Notes

Installation requires a hex socket driver sized for the socket head. Ensure the mating bore diameter matches the 8 millimeter shoulder tolerance before assembly. Do not use thread-locking compounds unless specified by the assembly design, as grade 12.9 fasteners may be sensitive to hydrogen embrittlement from certain chemical processes. Follow applicable ASME or ISO fastener installation guidelines for torque and fit class.
