Cement Board Screws

Cement Board Screws: What You Need to Know

Cement board screws, also known as backer board screws or tile board fasteners, are corrosion-resistant fasteners designed for securing cement boards to wood or metal studs. These screws feature serrated heads, sharp threads, and specialized drives like star or Phillips to provide flush, secure holds in wet or tiled environments. Available in various thicknesses (#9 and #10), with lengths ranging from 1-1/4 in. to 5 in., these screws are ideal for bathrooms, kitchens, and exterior applications where moisture resistance is critical.

Thickness:

• #9: The most common size for cement board applications, offering reliable grip and compatibility with both wood and metal studs. Ideal for all-purpose installation and compatible with both standard and heavy-duty boards.
• #10: A thicker, stronger option for heavy-load or high-stress areas. Used when extra holding power is required in thick backer board or layered assemblies.

Length:

• 1-1/4 in: Standard length for attaching cement board to flooring or wall studs. Works well in most residential applications where only a single board layer is needed.
• 1-5/8 in: Offers extra penetration depth for thicker materials or multi-layer setups. Ensures stronger holding power without compromising flush installation.
• 2-1/4 in: Designed for high-retention fastening in heavy-duty installations. Best used when attaching cement boards through insulation or thicker substrates.
• 5 in: Long-format screw used in unique structural or support-layer fastening situations. Provides deep anchoring where standard lengths fall short.
