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's Multi-Material screw handles the jobs that call for one fastener across different materials, thanks to a serrated, self-tapping thread built for wood. The T-20+ star drive keeps the bit seated so you're not fighting cam-out on long runs, and the high corrosion resistant finish means these hold up whether you're building outdoors or finishing work inside. Each box gives you 83 screws plus a matching driver bit, so you're ready to go right out of the box.

  • Size: No. 9 x 3-1/4"
  • Drive: T-20+ star, bit included
  • Thread: Serrated, self-tapping (not self-drilling)
  • Finish: High corrosion resistant, Grade 5 steel
  • Use: Indoor and outdoor, 83 screws per box

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.
