Value Collection R63004162 Shoulder Screw 3/8 in 18-8 Ss

Product Description

The VALUE COLLECTION R63004162 is a hex socket shoulder screw machined from 18-8 stainless steel. It features a 0.375-inch shoulder diameter and a 0.75-inch shoulder length, with a 5/16-18 UNC threaded end. The unthreaded shoulder section provides a precision bearing surface, making this fastener well suited for pivoting, rotating, or sliding applications in mechanical assemblies. Machinists, maintenance technicians, and fabricators install this type of shoulder screw wherever a controlled-clearance pin or shaft is needed within a bolted joint. The hex socket drive accepts a 3/16-inch hex key for installation in recessed or tight-clearance locations.

This shoulder screw is used in light industrial, mechanical, and equipment fabrication applications. The 18-8 stainless steel construction resists corrosion in wet or mildly corrosive environments, making it appropriate for food-service equipment, fluid-handling systems, and outdoor mechanical assemblies. The 5/16-18 UNC thread standard is widely compatible with standard tapped holes in that size. Sold individually with a minimum order quantity of 10 units.

Key Features

• Precision shoulder diameter of 0.375 inches provides a consistent bearing and pivot surface
• Shoulder length of 0.75 inches suits shallow-clearance assembly configurations
• 18-8 stainless steel construction offers corrosion resistance in wet and mildly harsh environments
• 5/16-18 UNC thread standard ensures broad compatibility with standard tapped holes
• 3/16-inch hex socket drive allows installation in recessed or confined spaces
• Minimum order quantity of 10 units makes this suitable for production and maintenance stocking

Compatibility

Designed as an OEM-style replacement or standard-fit shoulder screw for mechanical assemblies requiring a 3/8-inch shoulder diameter, 3/4-inch shoulder length, and 5/16-18 UNC threaded end in 18-8 stainless steel.

Installation Notes

Install using a 3/16-inch hex key; do not use an impact driver, as this may damage the hex socket recess or overtorque the threaded section. Ensure the mating tapped hole is clean and properly sized for 5/16-18 UNC threads before installation. De-energize and lock out any equipment before servicing assemblies that contain shoulder screws. Apply a thread lubricant or anti-seize compound if the screw will be installed in a stainless-to-stainless interface to reduce the risk of galling.
