Value Collection 711322PR Shoulder Screw 1/4 in 10-32 Alloy Steel

Product Description

The VALUE COLLECTION 711322PR is a 4140 alloy steel shoulder screw with a 0.250 inch shoulder diameter and a 1-1/4 inch shoulder length. The hex socket drive accepts a 1/8 inch hex key for installation. The uncoated finish exposes the base alloy steel, making it suitable for applications where a secondary coating or plating will be applied or is not required. This fastener is manufactured to ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards, ensuring dimensional consistency and mechanical performance. It is commonly installed by machinists, millwrights, and maintenance technicians in jigs, fixtures, and precision assemblies.

This shoulder screw is used in mechanical assemblies where a precision-ground shoulder acts as a bearing surface, pivot point, or guide for moving components. Typical applications include fixture plates, linkage assemblies, and tooling jigs in industrial and manufacturing environments. The 10-32 UNF thread engages standard tapped holes in steel and aluminum components. It is suited for both light-duty and moderate-load applications in machine shops and production facilities.

Key Features

• 0.250 inch shoulder diameter provides a precision bearing or pivot surface
• 1-1/4 inch shoulder length accommodates standard fixture and jig plate thicknesses
• 4140 alloy steel construction for strength and wear resistance
• 10-32 UNF thread for secure engagement in fine-thread tapped holes
• 1/8 inch hex socket drive for controlled torque installation with standard hex keys
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards for dimensional and mechanical conformance

Compatibility

Designed as a standard shoulder screw replacement for applications requiring a 1/4 inch shoulder diameter, 1-1/4 inch shoulder length, and 10-32 UNF thread in 4140 alloy steel per ANSI B18.3 and ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/8 inch hex key or matching hex socket bit. Ensure the mating tapped hole is clean and the thread is in good condition before installation. Do not overtighten, as the shoulder, not the thread, carries the primary load in most shoulder screw applications. Follow applicable facility or equipment maintenance procedures when servicing assemblies containing this fastener.
