Value Collection HCI51000275G-010BX Hex Head Cap Screw

Product Description

The VALUE COLLECTION HCI51000275G-010BX is a fully threaded hex head cap screw designed for general structural and mechanical fastening applications. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener delivers reliable corrosion resistance in outdoor, wet, or otherwise demanding environments. The 1-8 UNC thread size and 2-3/4-inch length under head make it well suited for heavy-duty bolted connections where a coarse-thread, inch-series fastener is required. Installers across plumbing, HVAC, electrical, and general mechanical trades reach for Grade 5 galvanized hex cap screws when code-compliant, corrosion-resistant bolted assemblies are needed.

This fastener is appropriate for residential and light commercial construction, equipment mounting, structural connections, and mechanical assemblies that require a UNC coarse-thread bolt with corrosion protection. The hot-dipped galvanized coating is commonly specified for exterior applications, pressure-treated lumber connections, and environments subject to moisture exposure. It is installed using a standard hex wrench, socket, or impact driver with the correct 1-inch drive size.

Key Features

• Grade 5 steel construction for high tensile strength in demanding fastening applications
• Hot-dipped galvanized finish provides superior corrosion resistance compared to electroplated alternatives
• Fully threaded along the full shank length for maximum thread engagement
• 1-8 UNC coarse-thread standard for broad compatibility with standard inch-series nuts and tapped holes
• 2-3/4-inch length under head suits medium to heavy structural bolting tasks

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with 1-8 coarse-thread nuts, washers, and tapped holes conforming to ASME B18.2.1 dimensional standards.

Installation Notes

Installation is performed by qualified tradespeople or experienced DIYers using a hex socket, wrench, or impact tool sized for the fastener head. Always use an appropriate flat washer and nut rated to the same or higher grade as the fastener. Torque to the project or equipment manufacturer specifications for Grade 5 fasteners. Inspect the galvanized coating for damage before installation, as coating integrity is critical to corrosion performance in exposed environments.
