Value Collection HCI50620650G-025BX Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION HCI50620650G-025BX 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 6-1/2 inches under the head. Manufactured from Grade 5 steel with a hot-dipped galvanized finish, this fastener delivers solid tensile strength combined with corrosion resistance suited for outdoor and moisture-exposed installations. It is a standard inch-series fastener installed with common hand and power tools. Tradespeople across plumbing, HVAC structural framing, electrical racking, and general construction rely on this type of fastener for secure, load-bearing connections.

This cap screw is appropriate for use in residential and light commercial construction, equipment mounting, structural steel connections, and utility framing. The hot-dipped galvanized coating makes it a practical choice for exterior applications, treated lumber connections, and environments where bare steel fasteners would corrode prematurely. The partial thread configuration allows for a smooth shank grip zone between the head and the threaded portion, which is typical for through-bolt and bolted-joint applications where clamping force is the priority.

Key Features

• 5/8-11 UNC thread for broad compatibility with standard inch-series hardware
• 6-1/2 inches length under head for use in thick material assemblies and structural connections
• Grade 5 steel construction provides medium-high tensile strength suitable for structural fastening
• Hot-dipped galvanized finish offers corrosion resistance for outdoor and wet environments
• Partially threaded shank provides a full grip zone for tight clamping in bolted joints
• Standard hex head drives with common wrenches, impact drivers, and sockets

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with 5/8-11 nuts, washers, and tapped holes conforming to ASME B18.2.1 dimensional standards for hex cap screws.

Installation Notes

Installation is typically performed by general contractors, ironworkers, or maintenance technicians using a standard 15/16-inch wrench or socket. Torque should be applied per the applicable structural or mechanical code for Grade 5 fasteners in the specific joint configuration. When used with treated lumber, verify the galvanized coating meets local code requirements for compatibility with the preservative treatment. Always inspect threads for damage before installation and replace any fastener that shows deformation or coating failure.
