Value Collection 711037PS Shoulder Screw 1/4in X 4in 10-24

Product Description

The VALUE COLLECTION 711037PS is a shoulder screw machined from 4140 alloy steel with an uncoated finish. The shoulder measures 0.25 inches in diameter and 4 inches in length, providing a precise bearing surface for rotating or sliding components. The 3/8-inch head diameter and 3/16-inch head height seat flush in standard counterbored holes. Drive is a 1/8-inch hex socket. The threaded section is 10-24 UNC, allowing secure engagement into mating tapped holes. This fastener is used in jigs, fixtures, linkages, and mechanical assemblies where a hardened, close-tolerance shaft is required within the fastener itself.

Shoulder screws of this type are common in manufacturing, tooling, and mechanical maintenance applications. The 4-inch shoulder length suits deeper assemblies where bushings, bearings, or spacers must be captured and allowed to pivot or translate freely. The 4140 alloy steel construction provides the strength and wear resistance needed in high-cycle or load-bearing fastener positions. Licensed machinists, toolmakers, and maintenance mechanics typically specify and install this type of hardware.

Key Features

• 0.25-inch shoulder diameter with 4-inch shoulder length for precise fit in standard 1/4-inch bored holes
• 4140 alloy steel construction for high tensile strength and wear resistance
• 10-24 UNC threaded end for engagement into standard tapped holes
• 1/8-inch hex socket drive for installation with standard Allen keys or hex bit drivers
• Uncoated finish — compatible with post-installation plating or coating if required
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies, jigs, fixtures, and tooling applications requiring a 1/4-inch shoulder diameter and 10-24 UNC threaded engagement.

Installation Notes

Install using a 1/8-inch hex key or hex socket driver. Ensure the mating tapped hole is clean and sized for 10-24 UNC thread engagement before driving. Do not apply torque to the shoulder surface. Power down or de-energize any assembly before servicing components that use this fastener as a pivot or guide pin.
