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 connections where a lag bolt would normally do the job - think ledger boards, beams, and other load-bearing framing. The serrated thread bites into wood fast without pre-drilling, and the washer head spreads out the load for a solid, lasting hold. A high corrosion-resistant finish means these hold up whether the connection is buried in a wall or exposed to weather outdoors.

  • Drive: T-40 (bit included)
  • Material: Grade 5 carbon steel, black finish

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.
