Value Collection HCI50620375G Hex Cap Screw 5/8-11 Grade 5 Galvanized

Product Description

The VALUE COLLECTION HCI50620375G is a partially threaded hex head cap screw designed for general structural and mechanical fastening applications. It features a 5/8-11 UNC thread size and measures 3-3/4 inches under the head. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener delivers solid tensile strength and corrosion resistance suitable for outdoor and exposed environments. The partial threading provides a smooth shank section, which helps maintain joint clamping force and reduces the risk of thread fatigue under load. Licensed tradespeople and contractors reach for this type of fastener in a wide range of structural and equipment assembly tasks.

This hex head cap screw is suited for residential and commercial construction, mechanical assemblies, equipment mounting, and structural connections where a standard inch-series UNC fastener is specified. The hot-dipped galvanized coating makes it a practical choice for outdoor installations, treated lumber connections, and environments with moderate moisture exposure. It is installed wherever a reliable 5/8-11 bolt is required and is compatible with standard 5/8-inch hex nuts and flat washers.

Key Features

• 5/8-11 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• 3-3/4 inches length under head with partial threading for a smooth shank bearing surface
• Grade 5 steel construction provides medium-strength tensile performance
• Hot-dipped galvanized finish delivers corrosion resistance for outdoor and exposed-environment use
• Inch measurement system; thread standard is UNC

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with 5/8-11 threaded nuts, inserts, and tapped holes in structural and mechanical applications.

Installation Notes

Installation is performed using a standard hex wrench, socket, or impact driver sized for the 5/8-inch hex head. Always ensure mating threads are clean and free of debris before driving the fastener. Consult applicable structural or mechanical codes for required torque values, as proper clamp load specifications vary by application and joint design. Shut down any connected equipment or de-energize any electrical systems before fastening components in place.
