Value Collection R52001250 Hex Head Bolt 5/8-11 Grade 2

Product Description

The VALUE COLLECTION R52001250 is a 5/8-11 UNC hex head bolt designed for general fastening applications in construction, mechanical assembly, and structural connections. This bolt features a hot-dipped galvanized finish over Grade 2 steel, providing corrosion resistance in outdoor and moderately harsh environments. The shank is partially threaded with a 2-inch length under head and a 15/16-inch hex drive. It conforms to ANSI/ASME B18.2.1 dimensional standards, making it a straightforward drop-in choice wherever a Grade 2 galvanized hex bolt of this size is called for by specification or code.

This bolt is suited for residential and light commercial construction, HVAC equipment mounting, plumbing support structures, electrical enclosure mounting, and general trade work requiring a corrosion-resistant fastener. The 5/8-11 thread size is commonly encountered in structural steel connections, pipe hangers, equipment bases, and unistrut assemblies. The hot-dipped galvanized coating makes it appropriate for outdoor, wet, or treated-lumber applications where bare steel fasteners would corrode prematurely.

Key Features

• 5/8-11 UNC thread for compatibility with standard nuts and tapped hardware
• Hot-dipped galvanized finish for corrosion resistance in outdoor and wet environments
• Partially threaded shank for improved clamping force and shear strength
• Grade 2 steel construction meeting ANSI/ASME B18.2.1 dimensional standards
• 15/16-inch hex head for use with standard wrenches and impact sockets
• 2-inch length under head suits medium-depth structural and equipment fastening tasks

Compatibility

Designed as a standard-dimension Grade 2 galvanized hex head bolt for general fastening applications conforming to ANSI/ASME B18.2.1 and ANSI/ASME B18.2.2. Accepts any standard 5/8-11 UNC nut or tapped component.

Installation Notes

Install using a 15/16-inch wrench, box end wrench, or impact socket. Ensure mating nuts or tapped holes are also 5/8-11 UNC thread to avoid cross-threading. When used in structural applications, consult applicable building codes for minimum torque and grade requirements, as Grade 2 has lower proof load values than Grade 5 or Grade 8 hardware. In treated-lumber applications, verify the galvanized coating weight meets local code requirements for the specific lumber treatment type.
