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

SPAX PowerLags are built for structural wood-to-wood work like framing, where you need a fastener that bites hard and stays put. The 5/16 x 8 in. size drives through serrated threads that cut their own path without a pre-drilled hole, and the washer head spreads load for a solid, flush connection. A T-40 drive bit comes in the pack, so you're not hunting for the right driver mid-job. High corrosion-resistant finish means these hold up whether the work is indoors or out.

  • Size: 5/16 in. x 8 in.
  • Drive: T-40, bit included
  • Head: Washer, Grade 5 carbon steel
  • Thread: Serrated, self-tapping (not self-drilling)
  • Finish: High corrosion resistant, black
  • 12 screws per clamshell pack

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.
