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

Designed for reliable, long-lasting wood fastening, the FastenMaster FlatLok No. 14 x 2-7/8 in. Torx Ttap epoxy-coated wood screws combine toughness with smart design. A flat head sits flush for a clean finished look, while the Torx Ttap drive delivers high torque and lower cam-out, speeding up installation even on larger projects. Built from carbon steel and finished with an epoxy coating, these screws excel in both indoor and outdoor environments where moisture and weather can challenge fasteners.

  • Size and efficiency: No. 14 dia with a 2-7/8" length, perfect for thick decking, framing, and structural wood connections.
  • Epoxy-coated carbon steel: Advanced corrosion resistance for outdoor use and moisture-prone areas, extending the life of your joints.
  • Flat head with flush countersink: Creates a neat, professional look by sitting level with the surface.
  • Torx Ttap drive: Superior grip and reduced cam-out for faster, more precise driving—especially helpful on dense lumber.
  • Coarse thread: Quick bite in softwoods and composite materials, delivering strong, dependable pulls with less effort.
  • Self-drilling tip: Enables easier starts and faster installations by reducing predrill requirements in many woods.
  • Generous quantity: 500 screws per bucket, making it ideal for large projects like decks, fences, and outdoor structures.
  • Indoor and outdoor versatility: Built to perform across diverse environments, from interior framing to exterior construction.

The FlatLok line stands out by pairing a robust epoxy coating with a practical design that tackles real-world challenges—whether you’re attaching framing members, securing decking boards, or fastening outdoor trim. Compared with traditional wood screws, the combination of Torx Ttap drive and self-drilling tip reduces drive time and minimizes bit wear, while the flat head provides a cleaner finish on visible surfaces. This makes FlatLok screws a reliable choice for professional carpenters, DIY enthusiasts, and contractors who demand consistent results on every project.

Ideal use cases

Deck framing and deck board installation, fence construction, outdoor sheds and pergolas, interior framing where a flush finish matters, and any wood-to-wood connection that benefits from strong, quick-driving fasteners. The epoxy finish helps resist rust in humid or damp environments, giving you peace of mind in outdoor settings.

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.
