Value Collection R63004283 Shoulder Screw 3/8in 18-8 Ss

Product Description

The VALUE COLLECTION R63004283 is a hex socket shoulder screw machined from 18-8 stainless steel, designed for precision fastening applications where a smooth, controlled shank is required between mating parts. The shoulder measures 3/8 inch in diameter and 1-1/2 inches in length, providing a precise bearing or pivot surface. The threaded end is 5/16-18 UNC. The hex socket drive accepts a 3/16-inch hex key for installation in confined spaces where a standard wrench cannot reach. This fastener is suited for machine assembly, jig building, fixture work, and mechanical linkage applications across industrial and trade settings.

Shoulder screws of this type are commonly used wherever a rotating or sliding component needs a precise locating pin with a clamping thread. Typical applications include pivot joints, guide pins for linear motion components, and hinge points in mechanical assemblies. The 18-8 stainless steel construction makes this screw appropriate for environments with moderate corrosion exposure, including wet or humid service conditions. Machinists, millwrights, and maintenance technicians working in manufacturing, HVAC equipment assembly, and general industrial maintenance will find this fastener useful across a wide range of applications.

Key Features

• 3/8-inch shoulder diameter provides a precise bearing and locating surface
• 1-1/2-inch shoulder length suits moderate-depth pivot and guide applications
• 5/16-18 UNC threaded end for standard imperial clamping
• 18-8 stainless steel construction offers good corrosion resistance in wet or humid environments
• 3/16-inch hex socket drive allows installation with a standard hex key in tight spaces

Compatibility

Designed as a standard shoulder screw for general industrial and mechanical assembly applications requiring a 3/8-inch diameter shoulder, 5/16-18 UNC thread, and hex socket drive.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the mating bore matches the 3/8-inch shoulder diameter for a proper fit before threading into the tapped hole. De-energize or lock out any equipment before replacing fasteners in live machinery per applicable safety procedures. Do not overtighten the threaded section, as the shoulder — not the thread — carries the primary load in most shoulder screw applications.
