Value Collection 711310PR Shoulder Screw 1/4in 10-32 Alloy Steel

Product Description

The VALUE COLLECTION 711310PR is a hex socket shoulder screw manufactured from 4140 alloy steel in an uncoated finish. The shoulder measures 0.25 inches in diameter and 0.5 inches in length, with a 10-32 UNF threaded end for secure fastening. The socket head accepts a 1/8 inch hex key drive and has a head diameter of 0.375 inches and a head height of 0.1875 inches. This screw meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards, making it a reliable choice for precision mechanical assemblies where a fixed bearing surface or a guided sliding fit is required.

Shoulder screws of this type are commonly used in jigs, fixtures, tooling plates, linkages, and mechanical assemblies where a precise cylindrical shoulder acts as a pivot point, bearing surface, or alignment feature. The 4140 alloy steel construction provides the hardness and tensile strength required for demanding industrial and maintenance applications. This fastener is appropriate for machinists, millwrights, and maintenance technicians working with light-duty mechanical assemblies in both production and repair environments.

Key Features

• Shoulder diameter of 0.25 inches (0.2500 decimal) for precise fit in bored or reamed holes
• Shoulder length of 0.5 inches provides a defined bearing or pivot surface
• 10-32 UNF threaded end for secure clamping below the shoulder
• 1/8 inch hex socket drive for installation with a standard Allen key
• 4140 alloy steel construction meets ASTM A574 mechanical requirements
• Uncoated finish suitable for use as-delivered or with added lubrication or plating

Compatibility

Designed as a standard shoulder screw for use in precision mechanical assemblies, jigs, fixtures, and tooling applications requiring a 0.25 inch shoulder diameter and 10-32 UNF thread specification per ANSI B18.3.

Installation Notes

Install using a 1/8 inch hex key; do not use impact drivers on socket head shoulder screws as this can damage the drive recess or distort the shoulder. Ensure the mating bore is sized to provide the appropriate fit for the intended application, whether clearance for rotation or a light press for alignment. Verify thread engagement depth in the receiving component meets minimum requirements per applicable fastener standards before applying torque.
