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

When you’re installing exterior tile or cement board, you need a fastener you can rely on from first drive to long-term performance. The Simpson Strong-Tie No. 9 x 1-5/8 in. L Square Galvanized Coarse Cement Board Screws (1500 pk) are engineered for durable, rust-resistant holding power in outdoor environments. These screws are purpose-built for cement board assemblies, delivering consistent bite and a flush finished surface for tiles and bedding materials.

Designed to meet the demands of outdoor installations, these screws pair a wafer head with a square-drive configuration. The dense, coarse thread provides strong gripping power in substrates commonly used with cement board, while the galvanized steel coating resists corrosion in moisture-rich settings. The 1-5/8 inch length strikes a balance between secure anchoring and minimizing board visibility, helping your tiling projects look clean and professional.

Why choose Simpson Strong-Tie cement board screws

  • Square-drive reliability – precise torque control and reduced cam-out for faster, more consistent driving.
  • Wafer head for flush seating – sits neatly against the cement board surface, promoting a smooth substrate for tile application.
  • Coarse-thread, galvanized steel – exceptional bite in wood or similar backing without sacrificing outdoor durability.
  • Outdoor-ready finish – galvanization protects against rust and corrosion in damp, exposed environments.
  • Bulk convenience – 1,500 screws in a boxed pack keeps your project moving without reordering delays.

Ideal use cases

  • Exterior tile installations on cement backer boards for patios, facades, and outdoor living spaces
  • Outdoor showers, pool surrounds, and damp-area tile projects where long-lasting fasteners are essential
  • Any cement board application in moisture-prone environments requiring a sturdy, corrosion-resistant fastener

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.
