Value Collection C52000487 Shoulder Screw 5/16 in 1/4-20

Product Description

The VALUE COLLECTION C52000487 is an 18-8 stainless steel shoulder screw designed for precision fastening applications where a fixed-diameter bearing surface is required. The shoulder measures 0.3125 inches (5/16 inch) in diameter and 2 inches in length, providing a smooth, accurately toleranced shank that acts as a pivot, spacer, or guide pin. The threaded portion is 1/4-20 UNC. Drive engagement is through a 5/32 inch hex socket. Machinists, millwrights, and maintenance technicians install these fasteners in fixtures, jigs, linkages, and mechanical assemblies requiring controlled rotational or sliding motion at the shoulder.

This shoulder screw is suited for light industrial, tooling, and mechanical assembly applications where corrosion resistance and dimensional consistency are priorities. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure or where material contamination is a concern. It is commonly installed in production fixtures, guide assemblies, and pivot mechanisms across manufacturing, maintenance, and facility operations settings. Each package contains 5 pieces, making it practical for both single repairs and small-batch assembly work.

Key Features

• 5/16 inch (0.3125 inch) shoulder diameter provides a precise bearing surface for pivot and guide applications
• 2 inch shoulder length accommodates thicker fixtures and multi-layer assemblies
• 1/4-20 UNC thread standard for broad compatibility with standard tapped holes
• 5/32 inch hex socket drive for installation with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction offers corrosion resistance in moderate-exposure environments
• Sold in a 5-piece package quantity

Compatibility

Designed as a standard UNC shoulder screw for use in any application requiring a 5/16 inch shoulder diameter, 2 inch shoulder length, and 1/4-20 threaded end in 18-8 stainless steel.

Installation Notes

Installation is performed with a 5/32 inch hex key or hex socket driver. Ensure the mating tapped hole is clean and properly sized for 1/4-20 UNC thread before installation. Do not overtighten, as the shoulder must remain free to rotate or slide against the mating bore in most applications. Power down or de-energize any equipment before servicing assemblies that incorporate these fasteners.
