Value Collection 711035PS Shoulder Screw 1/4 in 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711035PS is a hex socket shoulder screw machined from 4140 alloy steel in an uncoated finish. The shoulder measures 0.25 inches in diameter and 3.25 inches in length, providing a precision bearing surface for pivoting or sliding components. The 10-24 UNC threaded end anchors the fastener into a tapped hole, while the 3/8-inch diameter head seats flush or slightly above the mating surface. The hex socket drive accepts a 1/8-inch hex key for installation in confined spaces. Manufactured to ANSI B18.3 and ASTM A574 standards, this screw is suited for mechanical assemblies, jigs, fixtures, and precision linkage applications. Machinists, tool-and-die makers, and maintenance technicians are the typical installers.

Shoulder screws of this configuration are commonly used in manufacturing and industrial maintenance environments where a hardened, ground shoulder is needed to serve as a shaft, pivot pin, or guide post. The 4140 alloy steel construction offers good strength and wear resistance for moderately loaded bearing applications. This screw is appropriate for use in sheet metal fixtures, stamping dies, robotic end effectors, and general mechanical assemblies requiring a precise shoulder fit. The uncoated finish keeps dimensional tolerances tight without added plating buildup.

Key Features

• 0.25-inch shoulder diameter with 3.25-inch shoulder length for a long bearing surface
• 4140 alloy steel construction meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards
• 10-24 UNC thread for secure anchoring in standard tapped holes
• 1/8-inch hex socket drive allows installation in tight clearance areas
• 3/8-inch head diameter with 3/16-inch head height for low-profile seating
• Uncoated finish maintains tight dimensional tolerances

Compatibility

Designed as an OEM-style replacement or standard-specification shoulder screw for mechanical assemblies requiring a 1/4-inch shoulder diameter, 3-1/4-inch shoulder length, and 10-24 UNC thread. Conforms to ANSI B18.3 and ASME/ANSI B18.3 dimensional standards.

Installation Notes

Install using a 1/8-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the torque capacity of the 10-24 thread; refer to published torque tables for 4140 alloy steel fasteners at this thread size. Verify shoulder hole diameter in the mating part matches the 0.25-inch shoulder diameter for proper fit and function.
