Value Collection R57600590 Shoulder Screw 1/2 in 5 in 3/8-16

Product Description

The VALUE COLLECTION R57600590 is a shoulder screw machined from 18-8 stainless steel with an uncoated finish. The shoulder measures 0.5 inches in diameter and 5 inches in length, providing a precise bearing surface for rotating or sliding components. The threaded section is 3/8-16 UNC, and the fastener is driven by a 1/4 inch hex socket. The head measures 3/4 inches in diameter and 5/16 inches tall. Shoulder screws of this type are installed by machinists, maintenance technicians, and mechanical assemblers wherever a tight-tolerance pivot, guide, or spacer is required within a mechanical assembly.

This shoulder screw is suited for industrial machinery, jigs and fixtures, tooling applications, and general mechanical assemblies that require a smooth, hardened shoulder to serve as a shaft, pivot, or guide pin. The 18-8 stainless steel construction provides corrosion resistance appropriate for washdown environments, food-handling equipment, and outdoor or high-humidity service conditions. The uncoated finish maintains dimensional accuracy without adding coating thickness that could affect fit tolerances.

Key Features

• Shoulder diameter of 0.5 inches provides a precision bearing surface for rotating or sliding components
• Shoulder length of 5 inches accommodates deeper assemblies and stacked components
• 3/8-16 UNC thread is a widely used standard thread form for secure engagement
• 18-8 stainless steel offers corrosion resistance and good mechanical strength
• 1/4 inch hex socket drive allows installation with standard hex keys or socket drivers
• Uncoated finish preserves dimensional accuracy for close-tolerance applications

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies, jigs, fixtures, and tooling wherever a 1/2 inch shoulder diameter and 3/8-16 UNC thread specification is required.

Installation Notes

Installation is typically performed by machinists or mechanical maintenance technicians using a 1/4 inch hex key or socket driver. Ensure mating bore diameter matches the 0.5 inch shoulder diameter for proper fit and function. De-energize and lock out all equipment before installing or removing fasteners in powered machinery. Do not substitute thread size or shoulder diameter without verifying clearance and load requirements in the assembly design.
