National Hardware Group · Sourced directly through authorized manufacturer channels — the trusted brands your neighborhood hardware store carries. Learn how we keep the local store on the corner →
Independent hardware retailers often carry the same products — sometimes at competitive prices. Every order helps keep them on the corner.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.
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.
