Value Collection R63002323 Shoulder Screw 5/16 in 1/4-20

Product Description

The VALUE COLLECTION R63002323 is a hex socket shoulder screw machined from 18-8 stainless steel. It features a 5/16-inch shoulder diameter and a 1/2-inch shoulder length, with a 1/4-20 UNC threaded shank. The shoulder provides a precision bearing surface, making this fastener well suited for pivot points, linkages, and guided assemblies where a smooth, accurately dimensioned shaft is required. The hex socket drive accepts a 5/32-inch hex key for installation in confined spaces. Licensed machinists, maintenance technicians, and assembly professionals working in industrial, commercial, and light mechanical applications are the typical installers.

This shoulder screw is used in mechanical assemblies where a controlled-clearance shaft or pivot is needed. Common applications include jigs and fixtures, conveyor and linkage assemblies, tooling plates, and rotating or sliding component mounts. The 18-8 stainless steel construction resists corrosion in moderately wet or washdown environments, making it a practical choice for food-service equipment, marine hardware, and general industrial machinery. Sold individually; minimum order quantity is 10 units.

Key Features

• 5/16-inch shoulder diameter (0.3125 inches) provides a precision bearing and pivot surface
• 1/2-inch shoulder length for controlled depth of engagement
• 1/4-20 UNC threaded shank for broad hardware compatibility
• 18-8 stainless steel construction for corrosion resistance in moderate environments
• 5/32-inch hex socket drive allows installation in tight or recessed locations

Compatibility

Designed as a standard shoulder screw for use in mechanical assemblies, jigs, fixtures, and pivot applications requiring a 5/16-inch shoulder diameter and a 1/4-20 UNC threaded shank.

Installation Notes

Install using a 5/32-inch hex key or Allen driver. De-energize and lock out any equipment before fastener installation or replacement. Thread the screw in by hand first to confirm proper thread engagement and avoid cross-threading. Do not over-torque the threaded shank, as the shoulder must seat fully against its mating surface to function as an accurate pivot or guide.
