Coarse Thread Drywall Screws (½”~4″)

Coarse Thread Drywall Screws – Bugle Head Design for Flawless Drywall Installation

These Coarse Thread Drywall Screws are the essential fastener for professional and reliable interior construction, available in a comprehensive range of lengths from ½ inch up to 4 inches. The coarse thread is specifically optimized for fast driving and superior holding power in wood studs and framing.

The key to a professional finish is the bugle head design. This unique head flares out slightly, ensuring the screw dimples the paper surface of the drywall perfectly without tearing it, creating an ideal depression for joint compound (mud) and minimizing sanding. The black phosphate finish provides a basic level of corrosion resistance necessary for interior applications until the screws are covered and finished. The sharp needle point allows for quick, self-starting penetration without the need for pre-drilling.

Key Benefits

• Bugle Head Design: Gently countersinks into drywall, preventing paper tear-out and creating a perfect depression for finishing compound.

• Coarse Thread: Optimized for fast driving and secure, strong hold into wood studs and framing.

• Wide Size Range: Available from ½ inch to 4 inches, covering single-layer installation, thick sheathing, and multi-layer applications.

• Fast Self-Starting: Sharp needle point allows for quick penetration without the need for pre-drilling.

• Black Phosphate Finish: Provides a necessary level of corrosion resistance for interior use.

Perfect For

• Securing standard ½” or  ⅝” gypsum board panels to wood studs and joists.

• General interior framing, sheathing, and construction work.

• Remodeling projects requiring fast, reliable wood fastening.

Application Instructions

• Driving: Use a power drill or screw gun with a Phillips (or square/driver bit specific to the screw).

• Setting Depth: Drive the screw until the bugle head creates a slight dimple in the paper surface without breaking the paper entirely (use a dedicated dimpler attachment for consistent depth).

• Joint Compound: Cover the dimpled head with joint compound during the taping and finishing stages.

• Safety: Wear safety glasses during installation.

Pro Tips

• For maximum holding power, screws should penetrate the wood stud by at least 5/8 inch.

• To simplify driving and reduce dropped screws, use a magnetic bit holder.

• If the screw breaks the paper surface, remove it and place a new screw about an inch away to maintain structural integrity.

• Coarse thread is best for wood; ensure you use fine thread drywall screws for metal framing.
