ITW Buildex Cement Board Screws

A cement board screw is a fastener specifically designed to securely attach cement board, backer board, and similar materials to wood or light-gauge steel framing. It features a sharp, corrosion-resistant coating and a specially designed thread pattern that bites into dense, brittle boards without cracking or crumbling them. These screws are commonly used in tile installations, wet areas, and exterior applications where moisture resistance and long-term durability are critical. The self-countersinking head creates a flush finish that won’t interfere with tile or surface materials. Unlike standard drywall or wood screws, cement board screws are engineered to withstand the high alkalinity and moisture exposure of cement-based products. The result is a strong, secure, and code-compliant fastening solution for tough, high-performance building assemblies.
