Sculpted Strength for Outdoor Architecture

The rounded carriage head brings a refined, almost jewelry-like detail to gates, pergolas, and timber frames. I love how the smooth dome sits flush against wood, letting the grain remain the star. Pair these galvanized bolts with weathered cedar and matte black hardware for a balanced, artisanal look. Consider them the quiet luxury essential that keeps outdoor structures beautiful and enduring.


Build with confidence—choose these galvanized carriage bolts for long-lasting, weather-ready connections.

Affordable
Size: 16AWG -10FT 2Pin DT
Used them to install Morimoto 2 Banger pods on my vehicle. Casing for the wires is thick enough that will stand the weather and abrasion. I spliced them to make just one run, added braided sleeving (for looks and additional protection). The wire quality and thickness made the connection with waterproof connectors strong and durable. Saved me around 20 dollars as compared to brand name wires.
