In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

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

Secure your wood-to-wood projects with confidence using the HILLMAN 1/4 in. x 1-3/4 in. Zinc-Plated Steel Carriage Bolt. Built to withstand outdoor environments, this durable fastener blends a rounded carriage head with a square neck beneath for reliable grip during installation and a clean, finished look in your finished projects.

  • : 1/4 in. diameter, 1-3/4 in. long
  • : Steel for strength and longevity
  • : Zinc-plated to resist corrosion in exposed settings like decks, fences, and garden structures
  • : Coarse threading for easier driving into wood and solid bite
  • : Carriage bolt head with a square neck under the head to prevent rotation when tightening
  • : Boxed, 100 bolts per box, SAE unit of measurement
  • : Ideal for outdoor furniture frames, deck and balcony connections, gate assemblies, timber joinery, and other wood-to-wood constructions

Why this Hillman carriage bolt stands out: the zinc-plated finish delivers dependable rust resistance in outdoor or moisture-prone areas, while the coarse threads provide quick, secure engagement in soft and hardwoods. The square under the head helps keep the bolt from turning as you tighten the nut, making assembly faster and more accurate—even when working with large timbers or overhead hardware.

Practical tips for best results: pair these bolts with a matching nut and washer for a full-strength clamp, and pre-drill a pilot hole to prevent splitting in delicate woods. Use in conjunction with appropriate fasteners to ensure a tight fit that lasts season after season.

Whether you're updating a weathered deck, building a sturdy shed, or constructing outdoor furniture, these 100-piece Hillman carriage bolts give you reliable, ready-to-use hardware that supports robust, long-lasting connections.

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.
