Value Collection HCI206209000-025BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HCI206209000-025BX is a Grade 2 steel hex head bolt with a 5/8-11 UNC thread and a 9-inch length under head. The shank is partially threaded, leaving a smooth grip section near the head for shear-load applications and bolted joint assemblies. A zinc plating provides basic corrosion resistance suitable for indoor and light-duty outdoor use. This fastener meets ASTM A307 standards and is commonly installed by millwrights, ironworkers, HVAC installers, plumbers, and general contractors wherever a reliable medium-strength bolted connection is required.

This bolt is suited for structural, mechanical, and equipment-mounting applications across residential and commercial construction, HVAC equipment frames, piping supports, and light fabrication. The 5/8-11 UNC thread size is one of the most widely used coarse-thread specifications in North American trade work, making this fastener compatible with standard UNC nuts and threaded components of the same size and thread standard. The partial thread design is particularly useful when a smooth shank must pass through clearance holes before threading into a nut or tapped hole.

Key Features

• 5/8-11 UNC coarse thread — widely compatible with standard nuts and tapped holes
• 9-inch length under head for deep-reach or stacked-material applications
• Grade 2 steel construction meeting ASTM A307 fastener standard
• Partially threaded shank for improved shear performance in bolted joints
• Zinc plating for basic corrosion resistance in dry and light-moisture environments
• 15/16-inch hex drive fits standard open-end, box, and socket wrenches

Compatibility

Designed for use with 5/8-11 UNC standard nuts, washers, and threaded components conforming to inch-series UNC specifications. Compatible with any application requiring an ASTM A307 Grade 2 hex bolt in this thread and length configuration.

Installation Notes

Install using a 15/16-inch wrench or socket driver. Always use a properly rated nut and washer combination matched to the 5/8-11 UNC thread standard. Do not exceed the torque limits appropriate for Grade 2 fasteners; consult applicable structural or mechanical codes for torque requirements specific to your application. Inspect the zinc coating for damage before installation — compromised coating reduces corrosion resistance in exposed environments.
