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 wood-to-wood framing where you need real holding power, not just a fastener that looks the part. The 5/16 in. diameter and 3 in. length give you serious grip, and the serrated thread type bites in fast without pre-drilling. High corrosion resistant black finish means these hold up indoors or out, and each box comes with the T-40 driver bit you need to run them.

  • Diameter: 5/16 in., Length: 3 in.
  • Grade 5 carbon steel construction
  • Serrated thread, self-tapping (not self-drilling)
  • Washer head, T-40 drive with bit included
  • 50 screws per box, indoor/outdoor use

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.
