Value Collection HCI50620500G Hex Cap Screw 5/8-11x5 Grade 5 Galv

Product Description

The VALUE COLLECTION HCI50620500G is a partially threaded hex head cap screw designed for heavy-duty fastening applications across construction, mechanical assembly, and structural installations. It features a 5/8-11 UNC thread size with a 5-inch length under head, manufactured from Grade 5 steel with a hot-dipped galvanized finish. The hot-dip process provides a thick, adherent zinc coating that resists corrosion in outdoor, wet, and industrial environments. This fastener is installed with a standard hex wrench or impact driver and suits applications where full thread engagement at the nut or tapped hole is not required along the full shank length.

This screw is suited for structural connections, equipment mounting, and general mechanical assembly in residential and commercial construction. The 5/8-11 UNC thread is a widely used coarse-pitch standard, making it compatible with a broad range of nuts, washers, and threaded inserts of the same specification. The partial threading allows for a smooth shank section that can bear shear loads without thread engagement along that portion of the grip.

Key Features

• 5/8-11 UNC coarse thread for broad hardware compatibility
• 5-inch length under head suits thicker material stack-ups
• Grade 5 steel provides minimum proof load and tensile strength per SAE J429 standards
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and high-moisture environments
• Partial threading allows smooth shank to handle shear loads in structural applications
• Inch measurement system — compatible with standard SAE tooling

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use with 5/8-11 nuts, flat washers, lock washers, and threaded components meeting UNC coarse-thread specifications.

Installation Notes

Installation is performed with a 15/16-inch hex wrench or socket, which is the standard drive size for 5/8-inch fasteners. Torque to the fastener specification appropriate for the joint material and load requirements as defined by the design engineer or applicable code. Inspect the galvanized coating for damage before installation — field touch-up with cold galvanizing compound may be required on cut or abraded surfaces. Follow applicable structural or mechanical codes such as AISC, ASTM, or local building codes when used in structural connections.
