Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Designed for outdoor wood projects, the Hillman 1/2 in x 5-1/2 in Hot Dipped Galvanized Steel Carriage Bolt (25 pk) delivers dependable, corrosion-resistant fastening that stands up to rain, humidity, and seasonal shifts. Built from sturdy steel and finished with a hot-dipped galvanized coating, these carriage bolts are engineered to endure exposure while maintaining strong, reliable joints.

  • Size: 1/2 in diameter, 5-1/2 in length (grip length) for secure, deep-to-wood connections.
  • Finish: Hot-dipped galvanized coating provides long-lasting rust and corrosion resistance in outdoor environments.
  • Material & Grade: Steel construction with Grade 2 strength for everyday wood-to-wood fastening needs.
  • Thread Type: Coarse threads offer solid bite into soft and hardwoods, making installation quicker and easier.
  • Design Feature: Square under the head helps prevent turning during tightening, ensuring a tight, flush joint in wood assemblies.
  • Package: 25 bolts per box, ideal for bulk projects and consistent hardware replacement.

Commonly used in decks, fences, gates, pergolas, and timber framing, these carriage bolts are perfect when you need a clean, secure connection that remains durable in outdoor conditions. The 1/2-inch diameter paired with a 5-1/2-inch length provides ample grip for substantial wood thicknesses, while the HDG finish protects against rust in wet or coastal environments.

Practical tips for best results: pre-drill a pilot hole to minimize splitting, align the square neck with the wood grain to maximize grip, and pair with appropriate nuts and washers for a complete, weather-ready joint. Whether you’re building a new deck, repairing a fence, or assembling timber structures, this Hillman carriage bolt set delivers consistent performance and lasting value.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
