Value Collection 711207BR Shoulder Screw 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711207BR is a heavy-duty shoulder screw machined from 4140 alloy steel, designed for precision fastening applications where a controlled-diameter bearing surface is required. The shoulder measures 1.25 inches in diameter and 2.75 inches in length, providing a precise locating pin or pivot point within mechanical assemblies. The 7/8-9 UNC threaded section locks the fastener in place, while the 5/8-inch hex socket drive and a 1.75-inch head diameter allow for high-torque installation with standard hex keys. This fastener is installed by machinists, maintenance technicians, and mechanical assemblers across a wide range of industrial and OEM applications.

The 711207BR is suited for use in jigs, fixtures, linkages, die sets, and machine components where a hardened, close-tolerance shoulder is needed to guide movement or align mating parts. The uncoated 4140 alloy steel construction offers the strength required for load-bearing pivot and locating functions in both light industrial and heavy-duty manufacturing environments. It is sold individually and is appropriate wherever a large-diameter shoulder screw meeting ANSI B18.3 and ASME/ANSI B18.3 standards is specified.

Key Features

• 1.25-inch shoulder diameter provides a precision bearing and locating surface
• 2.75-inch shoulder length suits deep fixture and linkage applications
• 4140 alloy steel construction delivers high tensile strength and wear resistance
• 7/8-9 UNC thread for secure clamping engagement
• 5/8-inch hex socket drive for high-torque installation with standard hex keys
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw for industrial machinery, jigs, fixtures, die sets, and mechanical assemblies requiring a 1.25-inch diameter shoulder with a 7/8-9 UNC threaded end conforming to ANSI B18.3 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 5/8-inch hex key. Ensure the mating bore is machined to the appropriate tolerance for the 1.25-inch shoulder diameter before installation. Verify thread engagement depth is adequate for the application load before torquing. Follow applicable ASME and facility safety procedures when working with press-fit or close-tolerance fasteners in machinery.
