Timco Drywall Screws for Cement Board, 4.2x42mm, 200 Pack

The Timco Drywall Construction Timber Stud Cement Board Screws are specifically designed for fixing cement board to timber and thin sheet metal (maximum 0.6mm thickness). These screws feature a self-countersinking head for a secure and flush finish, ensuring a professional and clean installation every time.

The twin-cut point with a hi-low thread allows for rapid 'pick-up' and reduced torque, making installation quicker and easier. An exterior-grade coating provides superior corrosion resistance in damp or corrosive environments, surpassing standard fasteners in durability.

Key Features:

• Organic plating – Withstands 1,500 hours in a salt spray test, ensuring long-term performance.
• Ribs under the head – Improve countersinking for a flush fit.
• A1 Fire Classification – Suitable for high-safety applications.
• Compatible – Ideal for timber and thin sheet metal (max. 0.6mm).
