Value Collection KP64907 Carriage Bolt 5/8-11 2in Grade 8 25pk

Product Description

The VALUE COLLECTION KP64907 is a 5/8-11 carriage bolt designed for high-strength fastening applications where a clean, flush-bearing surface and resistance to rotation are required. Built to Grade 8 alloy steel and fully compliant with SAE J429, this bolt delivers the tensile strength needed in demanding structural and mechanical assemblies. The square neck seats firmly into wood or soft substrates to resist spin during installation. A zinc trivalent chromate finish provides corrosion resistance suitable for general industrial and construction use. Sold in a pack of 25 units, this fastener is well suited for contractors, maintenance professionals, and fabricators working with bolted connections that see significant load.

This carriage bolt is appropriate for residential and commercial construction, structural steel-to-wood connections, equipment mounting, and general industrial fabrication. The 5/8-11 UNC thread and 2-inch length under head suit a wide range of medium-to-heavy-duty bolted joint configurations. The fully threaded shank allows for maximum thread engagement across varying material thicknesses within that grip range.

Key Features

• Grade 8 alloy steel construction meets SAE J429 for high tensile and proof load strength
• 5/8-11 UNC fully threaded shank provides maximum thread engagement
• 2-inch length under head accommodates medium-to-heavy-duty joint stacks
• Square neck locks into substrate to prevent bolt rotation during nut tightening
• Zinc trivalent chromate finish offers corrosion resistance in general-duty environments
• Sold in a 25-count pack for job-site and shop efficiency

Compatibility

Designed as an OEM-style replacement or direct-use fastener compatible with any 5/8-11 UNC tapped or through-hole application requiring a carriage bolt profile and Grade 8 alloy steel strength rating.

Installation Notes

Carriage bolts of this size are typically installed by construction tradespeople, structural ironworkers, and maintenance mechanics. Power down or de-energize any equipment before fastening near live systems. Insert the bolt from the face side so the square neck seats fully into the material before applying a washer and nut from the opposite side. Torque to the appropriate Grade 8 specification for 5/8-11 fasteners per the applicable structural or equipment standard — do not exceed rated torque using impact tools without a torque-limiting socket.
