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

The Simpson Strong-Tie 10D 3 in. Siding Coated Stainless Steel Nail with a round head is built for exterior siding projects where confidence and longevity matter. This 25 lb box delivers a versatile, high-performance fastener that stands up to outdoor conditions while delivering a clean, professional finish.

  • Material and finish: Premium stainless steel with a durable coating for superior corrosion resistance in outdoor environments, helping your siding stand the test of time.
  • Exact dimensions: 12-gauge nails, 0.113" shank diameter, 3" length (10D callout), round head with a 7/32" head diameter, and a diamond point for easy starting.
  • Holding power: Ring shank design provides enhanced withdrawal resistance, making these nails ideal for wind-prone or high-stress exterior siding installations.
  • Packaging and quantity: Boxed packaging containing 3,000 nails per 25 lb container, ready for quick, efficient project work.
  • Indoor and outdoor use: Specifically designed for exterior siding applications, with corrosion resistance suitable for long-term outdoor exposure.
  • Brand assurance: From Simpson Strong-Tie, a trusted name in fastening solutions known for dependable performance on professional jobsites.

Who should use these nails? Contractors and serious DIYers tackling exterior siding installs, repaints, or siding refresh projects where long-lasting hold and a clean finish are priorities. The combination of stainless steel durability, ring shank gripping power, and the diamond point for smooth starts translates to fewer drive issues, less wood splitting, and a faster, cleaner installation process.

Practical tips for best results: pair these nails with a compatible 12-gauge siding nailer or hammer for consistent drive depth, keep nails dry and stored in a cool, covered area, and drive nails until the head sits flush with the siding surface. In windy or exposed environments, the ring shank helps resist pull-out, providing reliable performance over the life of the siding.

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.
