Value Collection A997110 Shoulder Screw 5/16 in 1/4-20

Product Description

The VALUE COLLECTION A997110 is a hex socket shoulder screw manufactured from 4140 alloy steel in an uncoated finish. The shoulder measures 5/16 inches in diameter and 2-1/4 inches in length, providing a precise cylindrical bearing surface for pivoting, guiding, or spacing components. The threaded portion is 1/4-20 UNC, driven by a 5/32-inch hex socket. This fastener meets ANSI B18.3 and ASTM A574 standards, making it a reliable choice for tooling fixtures, jigs, linkages, and precision assemblies across industrial and mechanical applications. Machinists, maintenance technicians, and mechanical assemblers typically install this type of fastener.

Shoulder screws of this configuration are commonly used in manufacturing fixtures, die sets, stamping tooling, and mechanical linkages where a hardened, ground bearing surface is required. The 4140 alloy steel construction provides the strength and wear resistance needed in high-cycle or load-bearing pivot points. This fastener is sold in a package quantity of five, with a minimum order quantity of one package, making it practical for both repair and production use.

Key Features

• 5/16-inch shoulder diameter provides a precise bearing surface for pivoting and guiding applications
• 2-1/4-inch shoulder length suits deeper fixture and linkage installations
• 4140 alloy steel construction offers high tensile strength and wear resistance
• 1/4-20 UNC threaded end for secure fastening into tapped holes
• 5/32-inch hex socket drive for reliable torque application in tight spaces
• Meets ANSI B18.3, ASME/ANSI B18.3, and ASTM A574 standards

Compatibility

Designed as a standard shoulder screw for use in industrial fixtures, jigs, tooling, and mechanical assemblies that require a 5/16-inch diameter shoulder, 1/4-20 UNC thread, and hex socket drive.

Installation Notes

Install using a calibrated 5/32-inch hex key or socket driver. Ensure the mating tapped hole is properly sized for 1/4-20 UNC thread engagement before installation. Power down or de-energize any machinery before accessing fastener locations in live equipment. Do not exceed the design load of the shoulder when used as a bearing surface in dynamic applications.
