Value Collection A996787 Shoulder Screw M6x1.00 Alloy Steel

Product Description

The VALUE COLLECTION A996787 is a metric shoulder screw designed for precision fastening applications where a controlled-diameter shoulder is required for alignment, pivoting, or bearing retention. The 8 mm shoulder diameter and 50 mm shoulder length provide a ground, close-tolerance surface that serves as a shaft or locating pin within mechanical assemblies. The M6x1.00 metric thread engages a tapped bore to pull the assembly tight while the shoulder itself carries the load. Manufactured from 12.9 grade alloy steel, this screw offers high tensile strength suitable for demanding industrial and mechanical service. Drive engagement is via hex socket, allowing installation with a standard Allen wrench or hex key driver.

This shoulder screw is suited for use in machine tooling, jigs and fixtures, die sets, automated equipment, and general mechanical assemblies requiring a precision shoulder for component alignment or rotational pivot points. The uncoated alloy steel finish is appropriate for applications where dimensional precision takes priority over corrosion protection. Installers working in fabrication, maintenance, and precision mechanical assembly will find this fastener compatible with standard metric tapped holes sized for M6x1.00 threads.

Key Features

• 8 mm shoulder diameter provides a precision locating or pivot surface
• 50 mm shoulder length accommodates deeper stack-up assemblies
• M6x1.00 metric thread for engagement into standard metric tapped bores
• 12.9 alloy steel construction delivers high tensile and proof load capacity
• Hex socket drive for reliable torque application with Allen key or hex driver
• Meets ASME/ANSI B18.3.3.M, BS 4168, ISO 7370, and ISO 7379 standards

Compatibility

Designed as an OEM-style metric shoulder screw for use in any mechanical assembly requiring an M6x1.00 tapped receiving hole and an 8 mm shoulder bore clearance.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician familiar with metric fastener standards. Ensure the receiving bore is sized appropriately for an 8 mm shoulder fit and the tapped hole is clean and free of debris before installation. Use a properly sized hex key or socket driver to apply torque; do not use an improperly sized driver that may strip the socket. Confirm shoulder length is appropriate for the total stack thickness of components being fastened before final assembly.
