Value Collection 711271BR Shoulder Screw 3/4 in 5/8-11

Product Description

The VALUE COLLECTION 711271BR is a hex socket shoulder screw machined from 4140 alloy steel and left uncoated for a clean, as-machined finish. The shoulder measures 0.75 inches in diameter and 0.5 inches in length, providing a precision bearing surface for rotating or sliding components. The threaded portion uses a 5/8-11 UNC thread form, and the drive is a 3/8-inch hex socket. The head stands 0.5 inches tall with a 1-inch diameter. This fastener is used by machinists, maintenance technicians, and assembly tradespeople working with jigs, fixtures, linkages, and precision mechanisms that require a controlled-diameter shaft integral to the fastener body.

This shoulder screw is suited for industrial and mechanical assembly applications where a precision shoulder must serve as a pivot point, guide pin, or bearing journal. Typical uses include die sets, punch press tooling, cam followers, and linkage assemblies in both light and heavy manufacturing environments. The 4140 alloy steel construction provides the strength and wear resistance demanded in high-load cycling applications. The UNC thread standard ensures broad compatibility with standard tapped holes in steel and aluminum fixtures.

Key Features

• Shoulder diameter of 0.75 inches provides a precision ground bearing and pivot surface
• 5/8-11 UNC thread for secure engagement in standard tapped holes
• 4140 alloy steel construction for high tensile strength and wear resistance
• 3/8-inch hex socket drive for use with standard Allen keys and hex socket tooling
• Uncoated finish maintains precise shoulder tolerances without coating buildup
• Meets ANSI B18.3 and ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw for use in fixtures, jigs, linkages, and mechanical assemblies requiring a 0.75-inch diameter precision shoulder with a 5/8-11 UNC thread.

Installation Notes

Installation is typically performed by machinists or maintenance mechanics using a 3/8-inch hex key or socket driver. De-energize and lock out any machinery before servicing assemblies containing this fastener. Thread engagement should be verified to meet the minimum depth requirements for the 5/8-11 thread before applying load. Do not use impact drivers on hex socket shoulder screws, as this can damage the socket or distort the shoulder.
