Value Collection 711170BR Shoulder Screw 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711170BR is a heavy-duty shoulder screw machined from 4140 alloy steel for demanding fastening applications. The shoulder measures 1 inch in diameter and 2-3/4 inches in length, providing a precise bearing surface for rotating or sliding components. Drive engagement is through a 1/2-inch hex socket. The head stands 5/8 inch tall with a diameter of 1-5/16 inches. The threaded portion is 3/4-10 UNC. This fastener ships uncoated and is suited for use by machinists, maintenance technicians, and mechanical assembly professionals who require close-tolerance shoulder dimensions.

Shoulder screws of this specification are commonly installed in jigs, fixtures, dies, cams, and linkage assemblies where a controlled-clearance pivot or guide pin is needed. The 4140 alloy steel construction provides adequate strength and wear resistance for both light production tooling and general industrial machinery. This screw meets ANSI B18.3 and ASME/ANSI B18.3 dimensional standards as well as ASTM A574 mechanical property requirements, making it suitable for critical mechanical assemblies across manufacturing and maintenance environments.

Key Features

• 1-inch shoulder diameter with 2-3/4-inch shoulder length for precise bearing and guide applications
• 4140 alloy steel construction for high tensile strength and wear resistance
• 3/4-10 UNC thread for secure fastening in standard tapped holes
• 1/2-inch hex socket drive for torque application with standard Allen keys or hex bits
• Uncoated finish suitable for use as-supplied or for post-installation coating by the end user
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard ANSI B18.3 shoulder screw for use in fixtures, jigs, dies, and mechanical assemblies requiring a 1-inch shoulder diameter and 3/4-10 UNC threaded engagement.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a 1/2-inch hex key or socket driver. Ensure the mating tapped hole is properly sized and cleaned before installation. Do not exceed the torque capacity of the 3/4-10 UNC thread for the material grade. Always verify shoulder fit and clearance in the bore before final assembly.
