Value Collection R63004682 Shoulder Screw 18-8 Stainless

Product Description

The VALUE COLLECTION R63004682 is a hex socket shoulder screw manufactured from 18-8 stainless steel, designed for precision fastening applications where a controlled-diameter shank is required. The shoulder measures 0.5 inches in diameter and 2 inches in length, providing an accurate bearing surface for rotating or sliding components such as linkages, pivot points, and alignment fixtures. The threaded portion is 3/8-16 UNC, driven by a 1/4-inch hex socket. This screw is installed by machinists, millwrights, and mechanical assemblers working across industrial, commercial, and light manufacturing environments.

This shoulder screw is suited for applications requiring a precision shaft or pivot within a mechanical assembly. The 18-8 stainless steel construction provides corrosion resistance appropriate for moderately wet or chemically exposed environments. Typical use cases include jigs, fixtures, cam followers, guide rails, and any assembly where a close-tolerance cylindrical shoulder must bear a load or serve as a pivot axis. The 1/4-inch hex socket drive allows installation in confined spaces where a standard hex head wrench cannot reach.

Key Features

• 0.5-inch shoulder diameter for precision fit in close-tolerance bores
• 2-inch shoulder length provides extended bearing surface for pivots and linkages
• 3/8-16 UNC thread for secure, standard-thread engagement
• 18-8 stainless steel construction offers corrosion resistance in wet or mild chemical environments
• 1/4-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 0.5-inch diameter shoulder with 3/8-16 UNC threading.

Installation Notes

Installation is typically performed by machinists or mechanical assemblers using a 1/4-inch hex key or socket driver. Ensure the receiving bore is sized to the shoulder diameter for proper fit and function before driving the screw. De-energize or lock out any machinery before servicing assemblies that incorporate this fastener. Do not overtighten — thread engagement should be confirmed against the mating component specification.
