Value Collection HCI50870600G Hex Cap Screw 7/8-9 X 6 in Grade 5

Product Description

The VALUE COLLECTION HCI50870600G is a 7/8-9 UNC hex head cap screw sized at 6 inches under the head, manufactured from Grade 5 steel with a hot-dipped galvanized finish. It is partially threaded, which provides a stronger shank grip in structural and mechanical fastening applications. The galvanized coating provides corrosion resistance for outdoor and high-moisture environments. This fastener is installed by HVAC technicians, plumbers, electricians, contractors, and maintenance professionals who need a reliable heavy-duty bolt for structural connections, equipment mounting, and general mechanical assemblies.

This screw is well suited for structural mounting tasks in residential and commercial trade applications, including equipment bases, pipe supports, duct hangers, electrical enclosure mounting, and similar load-bearing fastening work. The 7/8-9 UNC thread size is a standard coarse-thread designation commonly specified in structural and mechanical drawings. Its partially threaded body makes it appropriate for through-bolt installations where a smooth shank section between clamped members reduces bearing stress.

Key Features

• Grade 5 steel construction provides tensile strength suitable for structural and mechanical fastening
• Hot-dipped galvanized finish delivers corrosion protection for outdoor and wet-location use
• 7/8-9 UNC coarse thread is a widely standardized size for compatibility with matching nuts and tapped hardware
• Partially threaded shank reduces stress concentrations and suits through-bolt clamping applications
• 6-inch length under head accommodates thicker material stacks and structural members
• Sold individually, allowing single-piece procurement for repair and replacement work

Compatibility

Designed as a standard UNC inch-series hex head cap screw for use with 7/8-9 UNC hex nuts, lock nuts, and tapped holes in steel, iron, and structural lumber applications.

Installation Notes

This fastener should be installed by qualified tradespeople following applicable structural or mechanical specifications for the given application. Use the correct 7/8-9 UNC nut and hardened washer where specified, and ensure mating threads are clean and free of debris before assembly. Do not mix with metric or fine-thread hardware. When used in corrosive or outdoor environments, inspect the galvanized coating for damage before installation.
