Value Collection R63004442 Shoulder Screw 1/2 in 3/8-16 Ss

Product Description

The VALUE COLLECTION R63004442 is a shoulder screw machined from 18-8 stainless steel, designed for applications that require a precise, smooth bearing surface between mating components. The shoulder measures 0.5 inches in diameter and 0.5 inches in length, providing a controlled pivot or guide point. The threaded portion is 3/8-16 UNC, driven by a 1/4-inch hex socket drive. Maintenance technicians, machinists, and mechanical assemblers install this fastener where standard threaded bolts cannot provide the accurate shoulder geometry required for linkages, pivots, jigs, or fixture assemblies.

This shoulder screw is suited for light industrial, mechanical, and trade-maintenance applications where corrosion resistance and dimensional precision are required. The 18-8 stainless steel construction makes it appropriate for environments with moderate moisture exposure, including HVAC equipment panels, pump assemblies, plumbing fixture brackets, and general mechanical linkage points. It is sold individually with a minimum order quantity of 5 units per order.

Key Features

• 18-8 stainless steel construction provides corrosion resistance for wet and humid environments
• 0.5-inch shoulder diameter and 0.5-inch shoulder length deliver a precise bearing and pivot surface
• 3/8-16 UNC thread for secure fastening in standard tapped holes
• 1/4-inch hex socket drive compatible with standard hex keys and socket drivers
• Consistent dimensional tolerances support use in jigs, fixtures, and mechanical linkages

Compatibility

Designed as a standard shoulder screw for general mechanical assemblies requiring a 0.5-inch diameter shoulder, 3/8-16 UNC thread, and hex socket drive in 18-8 stainless steel.

Installation Notes

Installation is performed by machinists, mechanical technicians, or trade professionals using a 1/4-inch hex key or hex socket driver. Ensure the mating tapped hole is clean and threads are in good condition before driving the fastener. Do not overtighten, as the shoulder must remain free to serve as a bearing or pivot surface. Apply thread lubricant or anti-seize compound as appropriate for the service environment.
