Value Collection 711155BR Shoulder Screw 1 in 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711155BR is a heavy-duty shoulder screw machined from 4140 alloy steel, designed for precision alignment, pivoting, and guided-motion applications in mechanical assemblies. The shoulder measures 1 inch in diameter and 1-1/4 inches in length, providing a close-tolerance bearing surface for bushings, bearings, or link plates. Drive engagement uses a 1/2-inch hex socket drive. The uncoated finish preserves dimensional accuracy. Machinists, maintenance technicians, and industrial assemblers install this fastener where a hardened, accurately ground cylindrical shoulder is required to locate or retain a mating component under load.

This shoulder screw is suited for use in jigs, fixtures, linkages, cams, and pivot assemblies across general manufacturing, tooling, and maintenance environments. The 3/4-10 UNC thread engages tapped bores in steel plates and frames. The 5/8-inch head height and 1-5/16-inch head diameter provide a solid seating surface. It is appropriate for both original equipment builds and field replacement in industrial machinery where a standardized alloy-steel shoulder fastener is specified.

Key Features

• 1-inch shoulder diameter with 1-1/4-inch shoulder length for precise fit in close-tolerance bores
• 4140 alloy steel construction for high tensile strength and fatigue resistance
• 3/4-10 UNC thread for secure engagement in standard tapped steel bores
• 1/2-inch hex socket drive for installation with standard Allen or hex-bit tooling
• Uncoated finish preserves dimensional tolerances out of the box
• Meets ANSI B18.3 and ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or direct-install shoulder screw for mechanical assemblies requiring a 1-inch diameter, 1-1/4-inch length alloy-steel shoulder fastener with a 3/4-10 UNC threaded end, conforming to ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 1/2-inch hex key or socket bit driver. Ensure the mating bore diameter matches the shoulder diameter to the specified tolerance before assembly. De-energize and lock out any machinery before installing or replacing shoulder screws in live equipment. Do not exceed the rated thread engagement depth for the 3/4-10 UNC thread to avoid stripping the tapped bore.
