Value Collection 711303PR Shoulder Screw 10-32 4140 Alloy Steel

Product Description

The VALUE COLLECTION 711303PR is a shoulder screw designed for precision fastening applications where a smooth, close-tolerance shank is required to act as a pivot, guide, or spacer. The shoulder measures 0.25 inches in diameter and 0.25 inches in length, with a 10-32 UNF threaded section. Constructed from 4140 alloy steel with an uncoated finish, this screw delivers the hardness and tensile strength needed for mechanical assemblies subject to wear and cyclic loading. Drive engagement is via a 1/8 inch hex socket, requiring an Allen key or hex bit driver for installation.

Shoulder screws in this configuration are commonly used in jigs, fixtures, dies, linkage assemblies, and machine components where a precision bearing surface or pivot point is needed. The 10-32 thread is a fine-pitch unified thread well suited to thin material engagement and applications requiring controlled clamping force. This part is typically specified by mechanical engineers, maintenance technicians, and toolmakers working in industrial or manufacturing environments.

Key Features

• 0.25 inch shoulder diameter provides a precision bearing or pivot surface
• 0.25 inch shoulder length suits thin-stack or close-clearance assemblies
• 4140 alloy steel construction for high tensile strength and wear resistance
• 10-32 UNF thread for fine-pitch engagement in metal components
• 1/8 inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw conforming to ANSI B18.3 and ASME/ANSI B18.3 specifications, suitable for use wherever a 0.25 inch shoulder diameter, 10-32 threaded shoulder screw is called out in mechanical assembly drawings.

Installation Notes

Installation is performed with a 1/8 inch hex key or matching hex bit driver. Ensure mating bores are sized to the shoulder diameter tolerance specified on the assembly drawing before installation. Do not apply the socket drive to the threaded section. Verify thread engagement depth is sufficient for the application before torquing.
