Value Collection HCI50750800G Hex Cap Screw 3/4-10x8 Grade 5

Product Description

The VALUE COLLECTION HCI50750800G is a partially threaded hex head cap screw designed for heavy-duty fastening applications in structural, mechanical, and industrial assemblies. It features a 3/4-10 UNC thread size and an 8-inch length under head, providing substantial grip length for thick material stacks and through-bolt installations. The Grade 5 steel construction delivers a reliable tensile strength appropriate for demanding load-bearing connections. The hot-dipped galvanized finish provides corrosion resistance, making this fastener suitable for exterior and moisture-exposed environments. Trade professionals across construction, HVAC equipment mounting, mechanical contracting, and general fabrication rely on this screw size for structural connections.

This fastener is well suited for residential and commercial construction framing, equipment pad anchoring, structural steel connections, and general mechanical assembly where a coarse-thread, large-diameter cap screw is required. The partial thread configuration allows for greater shank bearing area against the material being fastened, which is preferred in applications where clamp load and shear resistance are priorities over full thread engagement through thin material.

Key Features

• 3/4-10 UNC coarse thread for fast engagement and strong clamping force
• 8-inch length under head accommodates thick material assemblies and through-bolt applications
• Grade 5 steel construction rated for medium-to-high strength fastening requirements
• Hot-dipped galvanized finish provides corrosion resistance for exterior and wet environments
• Partial thread design maximizes shank bearing area and shear resistance
• Inch measurement system with standard UNC thread form for broad compatibility with nuts and tapped holes

Compatibility

Designed as a standard 3/4-10 UNC hex head cap screw compatible with any 3/4-10 threaded nut, threaded insert, or tapped hole conforming to Unified National Coarse thread standards.

Installation Notes

Installation is performed by general contractors, ironworkers, mechanical contractors, and maintenance technicians using standard 1-1/8-inch hex drive sockets or wrenches. Follow applicable structural or mechanical codes, including AISC or applicable building codes, when using this fastener in load-bearing assemblies. Always use a matching Grade 5 or higher nut and appropriate flat washers to distribute load and protect mating surfaces. Do not mix galvanized fasteners with dissimilar metals in direct contact where galvanic corrosion may occur.
