Value Collection B10111 Shoulder Screw 8mm M6x1.00 Alloy Steel

Product Description

The VALUE COLLECTION B10111 is a metric shoulder screw engineered for precise locating, pivoting, and bearing retention in mechanical assemblies. It features an 8 mm shoulder diameter and a 20 mm shoulder length ground to close tolerances, providing the accurate positioning surface that bearings, bushings, and linkages require. The threaded portion is M6x1.00 metric and the drive is a hex socket, compatible with standard Allen keys and hex bit drivers. Manufactured from grade 12.9 alloy steel in an uncoated finish, this screw delivers high tensile and shear strength suited to demanding industrial and mechanical applications. Licensed machinists, maintenance technicians, and precision assemblers are the typical installers.

This shoulder screw is used wherever a hardened, close-tolerance shoulder is needed to guide motion or retain a rotating component. Common applications include jig and fixture construction, machine tool assemblies, robotic linkages, and hydraulic or pneumatic cylinder pivot points. The M6x1.00 thread engages a tapped bore while the 8 mm shoulder passes through a clearance hole in the mating component, creating a reliable pivot or slide surface. The hex socket drive allows installation in confined spaces where a wrench cannot reach. Sold in a package quantity of 10, this screw suits both small-batch repairs and light production runs.

Key Features

• 8 mm shoulder diameter and 20 mm shoulder length for precise bearing and bushing location
• Grade 12.9 alloy steel construction for high tensile strength and shear resistance
• M6x1.00 metric thread for engagement in standard tapped metric bores
• Hex socket drive allows installation with Allen keys or hex bit drivers in tight spaces
• Uncoated finish suitable for use as-supplied or with customer-applied coatings
• Meets ASME/ANSI B18.3.3.M, BS 4168, and ISO 7379 dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies requiring an 8 mm shoulder diameter, 20 mm shoulder length, M6x1.00 threaded shoulder screw conforming to ASME/ANSI B18.3.3.M, BS 4168, or ISO 7379.

Installation Notes

Installation is performed by machinists or mechanical technicians using a properly sized hex key or hex bit driver. Ensure the mating clearance hole matches the 8 mm shoulder diameter and the tapped bore is clean and correctly sized for M6x1.00 thread engagement before installation. De-energize and lock out any machinery before replacing or installing shoulder screws in live assemblies. Do not over-torque; consult applicable fastener standards for grade 12.9 torque guidance specific to your assembly.
