Value Collection 711158BR Shoulder Screw 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711158BR is a hex socket shoulder screw machined from 4140 alloy steel, designed for precision fastening applications where a controlled-diameter shoulder is required. The 1-inch shoulder diameter and 2-inch shoulder length provide a smooth bearing surface for pivoting, sliding, or locating components. The 3/4-10 UNC threaded shank and 1/2-inch hex socket drive allow installation with a standard hex key. This screw ships in an uncoated finish. Mechanical assembly technicians and maintenance professionals install this type of fastener in jigs, fixtures, linkages, and machine components.

Shoulder screws of this type are used in light and heavy industrial assemblies where a precision-ground shaft surface is needed to guide motion or serve as a pivot point. The 4140 alloy steel construction provides good tensile strength and wear resistance for demanding mechanical applications. The hex socket head keeps the fastener low-profile and allows torque application in confined spaces. Typical installations include die sets, fixture plates, robotic linkages, and mechanical assemblies requiring repeatable positioning.

Key Features

• 1-inch shoulder diameter with 2-inch shoulder length for precise bearing and locating surface
• 4140 alloy steel construction for strength and wear resistance
• 3/4-10 UNC thread standard for compatibility with standard tapped holes
• 1/2-inch hex socket drive for installation with a standard Allen or hex key
• 5/8-inch head height and 1-5/16-inch head diameter for broad seating surface
• Uncoated finish; meets ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or standard-spec shoulder screw for industrial mechanical assemblies requiring a 1-inch diameter, 2-inch shoulder length, 3/4-10 UNC threaded fastener.

Installation Notes

Installation requires a 1/2-inch hex key or Allen driver. Ensure the mating tapped hole is clean and matches the 3/4-10 UNC thread specification before installation. De-energize and lock out any machinery before servicing fasteners in moving assemblies. Do not exceed the torque capacity of the fastener or the mating material.
