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

Engineered for outdoor toughness, the Simpson Strong-Tie 6 in. H x 6 in. W 7 Ga. Galvanized Steel Column Base is the reliable foundation for vertical posts in decks, porches, and pergolas. Constructed from 7-gauge galvanized steel, it delivers the load-bearing strength you expect from a Simpson base while standing up to rust, moisture, and exposure to the elements.

  • 7-gauge galvanized steel construction provides superior strength and stiffness to support outdoor framing anchors and posts.
  • 6 in. height by 6 in. width footprint designed to accommodate standard 6x6 posts for a secure, stable connection.
  • Galvanized coating delivers long-lasting corrosion resistance, ideal for exterior installations and damp environments.
  • Trusted Simpson Strong-Tie engineering ensures reliable performance in structural framing applications.
  • Load distribution and post stability help minimize post movement, keeping decks, railings, and pergola structures plumb and true over time.

Where you’ll use it

Perfect for outdoor framing projects that require a rugged, durable post base. Use this column base to anchor deck posts, porch columns, railing posts, or pergola supports, delivering a solid foundation that resists weathering and deformation even after years of use.

Why it stands out

What makes this base unique is the combination of heavy-gauge steel and a compact, outdoor-ready profile. The 7-gauge wall thickness provides real strength without adding unnecessary bulk, while the galvanized finish protects against corrosion, making it suitable for exposed locations and coastal environments.

Practical tips & considerations

  • Ensure proper installation alignment to keep posts square and aligned with beams and rails.
  • Pair with appropriate exterior-grade anchors and fasteners suitable for your concrete or substrate, following local building codes.
  • Regularly inspect the base for signs of corrosion or wear and re-secure if needed to maintain structural integrity.

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.
