Value Collection 711150BR Shoulder Screw 3/4 in 6-1/2 in 5/8-11

Product Description

The VALUE COLLECTION 711150BR is a hex socket shoulder screw machined from 4140 alloy steel for use in precision mechanical assemblies. The shoulder measures 0.75 inches in diameter and 6.5 inches in length, providing an accurate bearing surface for pivoting parts, linkages, jigs, and fixtures. The threaded portion is 5/8-11 UNC, and drive engagement requires a 3/8 inch hex socket or Allen key. The head is 1 inch in diameter and 0.5 inches tall. This fastener ships uncoated and meets ANSI B18.3 and ASTM A574 standards. It is installed by machinists, millwrights, and maintenance technicians in industrial, manufacturing, and tooling applications.

This shoulder screw is suited for applications where a precision cylindrical shaft is needed to guide or retain a component while the threaded end anchors into a tapped hole. Common uses include fixture plates, die sets, robotic linkages, conveyor components, and pivot assemblies. The 4140 alloy steel construction provides high tensile strength and wear resistance appropriate for demanding mechanical environments. The uncoated finish is standard for applications where dimensional accuracy matters more than corrosion resistance.

Key Features

• 0.75 inch shoulder diameter provides a precise bearing and locating surface
• 6.5 inch shoulder length accommodates deep fixture or linkage installations
• 5/8-11 UNC thread for secure anchoring in standard tapped holes
• 4140 alloy steel construction for high tensile strength and wear resistance
• 3/8 inch hex socket drive for installation with standard Allen tooling
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or direct-fit shoulder screw for mechanical assemblies requiring a 0.75 inch diameter shoulder, 6.5 inch shoulder length, and 5/8-11 UNC threaded end in standard tapped steel or aluminum plates.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 3/8 inch hex key or socket driver. Ensure the mating tapped hole is clean and dimensionally correct for 5/8-11 UNC thread engagement before installation. De-energize and lock out any machinery before replacing shoulder screws in live assemblies. Do not over-torque; consult applicable engineering specifications for the assembly to determine the correct clamp load.
