Hillman Fasteners 812626 Galvanized Carriage Bolt 1/2-13x6 25pk

Product Description

The HILLMAN FASTENERS 812626 is a galvanized carriage bolt designed for structural fastening applications in wood, metal, and composite assemblies. Sized at 1/2-13 x 6 inches, this bolt features a smooth, domed head and a square neck that seats into the material to prevent rotation during installation. The hot-dip or electro-galvanized finish provides corrosion resistance suited for outdoor, pressure-treated lumber, and damp-environment applications. Sold in a 25-count box, this SKU is appropriate for contractors, framers, deck builders, and maintenance tradespeople who need quantity fasteners on hand for larger jobs.

Carriage bolts in this size range are commonly used in deck framing, dock construction, pergola assembly, fence post hardware, and general structural wood connections. The 1/2-13 thread designation means a 1/2-inch nominal diameter with 13 threads per inch, compatible with standard 1/2-inch hex nuts and washers. This pack configuration suits job-site use where multiple connections are required in a single work session.

Key Features

• 1/2-13 x 6 inch carriage bolt with full coarse-thread specification
• Galvanized finish for corrosion resistance in outdoor and treated-lumber applications
• Domed head with square neck prevents rotation during nut tightening without a second wrench
• 25-count pack quantity suitable for multi-connection framing and structural work
• Standard 1/2-inch diameter compatible with common hex nuts, washers, and structural connectors

Compatibility

Designed for use with standard 1/2-inch hex nuts and flat washers in wood-to-wood and wood-to-metal structural connections. Compatible with typical 1/2-inch hardware used in residential and light commercial framing, deck construction, and outdoor structural assemblies.

Installation Notes

Installation is performed by drilling a clean hole matching the bolt diameter through the mating materials, then driving the bolt through so the square neck seats flush and locks against rotation. A standard box-end wrench or socket is used to tighten the nut from the opposite side. Follow applicable building codes, such as the International Building Code or local structural requirements, for minimum fastener spacing and edge distances. Always use an appropriately rated washer under the nut when fastening into soft wood to prevent pull-through.
