Value Collection HCI50870650G Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION HCI50870650G is a 7/8-9 hex head cap screw measuring 6-1/2 inches under the head, manufactured from Grade 5 steel with a hot-dipped galvanized finish. The partial threading follows the UNC thread standard, making it suited for clamped-joint fastening applications where the smooth shank provides added shear strength. The hot-dipped galvanized coating delivers corrosion resistance in outdoor, humid, or moisture-exposed environments. This fastener is measured by the Inch system and weighs approximately 1.27 pounds per unit. It is a standard industrial fastener appropriate for structural, mechanical, and trade assembly work across HVAC, plumbing, and general construction applications.

This hex head cap screw is used in structural and mechanical fastening where a partially threaded, heavy-duty bolt with corrosion resistance is required. Typical applications include equipment mounting, steel-to-steel connections, treated lumber attachments, and exterior or outdoor installations where galvanized protection is necessary. It is commonly installed by HVAC technicians, pipefitters, electricians, and general construction trades as part of equipment brackets, supports, and frame assemblies.

Key Features

• Grade 5 steel construction for high tensile strength and reliable clamped-joint performance
• Hot-dipped galvanized finish provides heavy-duty corrosion resistance for outdoor and wet environments
• Partial threading along UNC standard for superior shear resistance in structural applications
• 7/8-9 thread size with 6-1/2 inch length under head for deep fastening reach
• Inch measurement system for straightforward compatibility with standard tooling

Compatibility

Designed as a standard UNC-thread hex head cap screw suitable for use with 7/8-9 nuts and tapped holes in inch-measurement fastening applications across structural, mechanical, and trade installation assemblies.

Installation Notes

Install using a standard hex socket or open-end wrench sized for a 7/8-9 fastener. Power down or de-energize any equipment before fastening components in electrical or HVAC assemblies. Do not substitute this Grade 5 fastener in applications specifying Grade 8 or higher without verifying structural requirements. Follow applicable building and mechanical codes for torque and fastener grade requirements on structural connections.
