Value Collection HCI50750350G Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION HCI50750350G is a partially threaded hex head cap screw designed for structural and mechanical fastening applications. It features a 3/4-10 UNC thread size and measures 3.5 inches under the head, providing substantial grip length for heavy-duty connections. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener offers reliable corrosion resistance in outdoor, wet, or exposed environments. It is commonly installed by contractors, millwrights, HVAC riggers, plumbers, and electricians wherever code-compliant mechanical fastening is required on structural steel, equipment bases, or mounting frames.

This cap screw is suited for general industrial and construction fastening tasks where a coarse-thread UNC fastener with a standard hex head is required. The partial thread shank allows it to bear shear loads more effectively than a fully threaded fastener of equivalent length, making it well suited for bolted joints where the unthreaded shank spans the mating material. Typical applications include equipment mounting, structural steel connections, framing anchors, and trade-service panel installations.

Key Features

• 3/4-10 UNC coarse thread for broad compatibility with standard hex nuts and tapped holes
• 3.5-inch length under head accommodates thicker mating materials and stacked assemblies
• Grade 5 steel construction meets medium-strength structural fastening requirements
• Hot-dipped galvanized finish provides corrosion resistance in outdoor and wet service conditions
• Partially threaded shank improves shear load performance in bolted joint applications

Compatibility

Designed as an OEM-style replacement or standard-stock hex head cap screw for use with 3/4-10 UNC hex nuts, flat washers, and lock washers in general structural and mechanical fastening applications.

Installation Notes

Installation of this fastener is within the scope of any licensed trade professional performing structural or mechanical assembly work. Always verify the mating thread is 3/4-10 UNC before driving the fastener to avoid cross-threading. Use a properly rated torque wrench and follow applicable fastener torque tables from the governing code or equipment manufacturer for the joint class. Inspect the galvanized coating for damage prior to installation in corrosive or marine environments, and use compatible galvanized or stainless hardware throughout the joint assembly.
