Fiber Cement Screws for Wood Framing

These screws make all the difference when it comes to secure and durable fastening of fiber cement and Hardie board siding. 

Here are some key things to remember:

  • Use our 316 stainless steel fiber cement siding screws to attach fiber cement siding to wood or stress skin panels.
  • 316 stainless steel fiber cement siding screws are designed for saltwater environments. This makes them ideal for coastal homes, waterfront projects, and exterior renovations.

Engineered for Proper Fiber Cement Fastening

Fiber cement is dense and inflexible, which is why drywall screws are insufficient as fasteners. They cannot sit flush. They tend to act as wedges that create pressure, which, in turn, leads to cracking and splitting. 

Experience the difference with dedicated fiber cement fasteners. 

  • All fiber cement screws offered have a wafer head with self-countersinking nibs.
  • The fiber cement screw made from 410 stainless steel should be used to attach fiber cement siding through furring strips to steel studs.
  • Hardie board screws combine a superior hold with a clean finish, securing fiber cement boards for all your outdoor projects.

FAQs

Can I use drywall screws to install fiber cement siding?

No. Drywall screws are not designed for fiber cement products. Unlike fiber cement screws, drywall screws lack the head design needed to properly seat dense cement boards. Instead of pulling the material tight, they can create pressure that leads to cracking, edge blowout, or premature fastener failure.

Drywall screws also lack the corrosion resistance required for exterior applications. For professional results, always use fasteners specifically engineered for fiber cement siding and follow the siding manufacturer's installation requirements.

What's the difference between the 316 stainless and 410 stainless fiber cement screws?

Both have their place on the jobsite, and the right choice depends on the application.

  • 316 stainless steel provides exceptional corrosion resistance, making it the preferred option for coastal construction, docks, waterfront homes, and other high-moisture environments.
  • 410 stainless steel is heat-treated for greater hardness, allowing it to be drilled through fiber cement and light-gauge steel with a lower risk of damaging the drive recess. It's commonly used when fastening through furring strips into steel studs.

If you're installing Hardie board screws near saltwater, 316 stainless steel typically offers the best long-term protection. For steel framing applications, 410 stainless steel often provides the ideal combination of strength and drilling performance.

Do I need to pre-drill before installing fiber cement screws?

In most field installations, pre-drilling isn't necessary when using quality fiber cement screws. Their cutting points are designed to penetrate dense fiber cement while reducing the risk of board damage.

Pre-drilling is still considered a best practice when:

  • Fastening within 2 inches of board edges or corners
  • Installing thicker fiber cement products
  • Using screws for hardie board siding made from 316 stainless steel, which is slightly softer than heat-treated 410 stainless steel
  • Working in colder temperatures, where fiber cement can become more brittle

For the best results, always follow the siding manufacturer's fastening schedule, spacing requirements, and installation instructions. Proper fastener selection and installation help maximize the performance and lifespan of your fiber cement siding system.
