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.

Why these screws stand out

The Cortex No. 10 x 2-1/2" deck screws are designed to deliver dependable performance in decking applications where size, drive type, and head shape matter. The Torx Ttap drive provides a secure fit with less cam-out, so you can drive screws cleanly and consistently. The button head creates a sleek surface profile that complements the deck’s lines, while the coarse thread ensures solid engagement with deck boards. With a generous 224-count per bucket, you’re equipped to complete substantial deck sections or multiple projects without reordering mid-way.

Ideal uses and scenarios

  • New deck installations where a standard No. 10 screw size fits your board material and spacing
  • Repairs or upgrades to bring a refreshed, uniform look across existing decks
  • Projects requiring a clean finished surface with fewer visible fasteners on the deck face
  • DIY weekend builds or professional deck installations that value consistent batch quantities

Tips for best results

  • Pair with the appropriate Torx Ttap driver bit to maximize drive accuracy and reduce stripping
  • Match screw length to deck board thickness to ensure proper seating without over-penetration
  • Organize fasteners by project area using the bucket format to keep workflow efficient on-site

Choose the FastenMaster Cortex No. 10 x 2-1/2" deck screws for a dependable, professional finish that supports both indoor and outdoor decking projects. The combination of size, drive, and head style is tailored to streamline installation while delivering a clean, lasting deck surface.

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.
