Value Collection R63039482 Hex Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION R63039482 is a hex head cap screw designed for general fastening applications in industrial, mechanical, and trade service environments. Manufactured from 18-8 stainless steel, this fastener offers solid corrosion resistance suitable for both indoor and outdoor installations. It features a 7/8-9 thread size on a Unified National Coarse (UNC) thread standard, with a length under head of 1-1/2 inches and a 1-5/16 inch hex drive. Plumbers, HVAC technicians, electricians, and general contractors use fasteners of this type when securing equipment panels, brackets, flanges, and structural components where corrosion resistance is a priority.

This hex head cap screw is suited for applications requiring a corrosion-resistant, inch-system fastener in residential, commercial, and light industrial settings. The UNC thread form makes it compatible with standard tapped holes and nuts in the 7/8-9 thread family. Common installation scenarios include equipment mounting, pipe support bracketing, and structural connections where stainless steel is specified to resist moisture or chemical exposure.

Key Features

• 18-8 stainless steel construction provides reliable corrosion resistance in wet or humid environments
• 7/8-9 UNC thread form mates with standard inch-system tapped holes and nuts
• 1-1/2 inch length under head suits medium-depth fastening applications
• 1-5/16 inch hex head accommodates standard open-end, box, or socket wrenches
• Inch measurement system compatible with common trade fastener standards

Compatibility

Designed as a standard inch-system hex head cap screw for use in any application specifying a 7/8-9 UNC thread fastener in 18-8 stainless steel.

Installation Notes

Install using an appropriately sized open-end, box-end, or socket wrench sized for a 1-5/16 inch hex head. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading. Follow applicable mechanical or structural codes for torque requirements based on joint design and load. Stainless steel fasteners are susceptible to galling — apply an anti-seize compound when specified by the application or manufacturer guidelines.
