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

About Product Overview

This is Milwaukee's Master set, a 366-piece mechanic's tool collection that ships prefilled in a Packout case instead of a flimsy blow-molded tray. That matters when you're moving a full toolset between the shop and the truck - the case stacks, locks, and holds up to the abuse a job site or garage dishes out.

The set covers 1/4", 3/8", and 1/2" drive sizes, so you're not stuck swapping between separate sets when the job calls for a smaller socket or more torque. Sockets and accessories are impact rated, which means they're built to take the shock loads from impact drivers without cracking or rounding out - useful for anyone doing real automotive or equipment repair, not just occasional bolt-turning. Chrome finish on steel construction resists corrosion and cleans up easily after greasy jobs.

This is a set for a serious home mechanic, a shop tech building out a rolling cart, or anyone tired of hunting for the one socket that's gone missing from a cheaper set. With 366 pieces, it's meant to be the last mechanic's set you buy.

  • Impact rated sockets and accessories

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.

Ask our counter. Or theirs.

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.

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 familiar 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.
