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

When you need a reliable fastener for wooden connections, the Hillman 1/4 in. x 2-1/4 in. Zinc-Plated Steel Carriage Bolt is up to the task. Built for steady, long-lasting performance, this bolt combines sturdy steel with a protective zinc finish to resist rust in a variety of environments. It’s the go-to choice for furniture, framing, decks, and other projects where a clean, non-threaded head is preferred.

  • Size and compatibility: 1/4-inch diameter with a 2-1/4-inch length. Designed to work with corresponding nuts and washers for secure, flush mounting in wood or approved metals.
  • Material and finish: Made from durable steel and coated with zinc plating for corrosion resistance, making it suitable for indoor and covered outdoor applications.
  • Head and threading design: Smooth, rounded carriage bolt head paired with a coarse thread that bites into wood quickly, helping you achieve solid grip without damaging the material.
  • Unique construction benefit: The square under the head prevents turning as you tighten the nut, enabling easy installation in scenarios where access is limited to one side.
  • Packaging: Sold as a boxed, single-piece bolt—ideal for orders where you need just one precisely sized fastener per package.

Ideal uses and practical applications

Perfect for assembling or repairing wooden components where a clean, finished appearance is important. Use it to secure hinge plates to wooden doors or frames, fasten rails or gate hardware, anchor posts to wooden bases, or join furniture frames where a smooth, rounded head is desired. Its Grade 2 steel construction provides dependable strength for general-purpose projects without the need for specialized hardware.

Installation tips for best results

  • Pair the carriage bolt with a matching nut and a flat washer to distribute load and prevent pull-through.
  • Align the bolt with a properly sized pilot hole to minimize wood splitting and to ensure a snug fit.
  • Tighten the nut evenly with a wrench to draw the bolt head firmly against the surface while the square under the head helps keep the bolt from turning.
