1¼” Coarse Thread Drywall Screws 100pcs

1-1/4″ Coarse Thread Drywall Screws (100pcs)

Coarse Thread Drywall Screws – Bugle Head, Coarse Thread for Reliable Wood Framing Installation

These 1-1/4″ Coarse Thread Drywall Screws are the fundamental fastener for professional and reliable interior construction using wood framing. The coarse thread (often referred to as W-Type) is specifically engineered to cut and hold quickly and securely into wood studs, providing exceptional holding power and speeding up the installation process. Supplied in a convenient 100-piece box, they are ideal for standard single-layer drywall installation and repair jobs.

The most critical design feature is the bugle head. This unique head shape countersinks perfectly without tearing the gypsum board’s paper surface, creating a clean, shallow dimple that is ideal for applying and finishing with joint compound (mud). The black phosphate finish provides necessary corrosion resistance for interior use until the screws are covered and painted.

Key Benefits

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

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

• Standard 1-1/4″ Length: Ideal size for fastening single-layer 1/2″ or 5/8″ drywall panels to wood studs.

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

• Phosphate Finish: Black phosphate coating provides necessary corrosion resistance for interior applications until covered.

Application Instructions

• Driving: Use a power drill or screw gun with a Phillips driver bit.

• 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 beyond the total thickness of the gypsum board.

• Use a magnetic bit holder to simplify driving screws in awkward positions.

• Coarse thread is mandatory for wood framing; use fine thread drywall screws for metal framing.

• Check the torque setting on the drill to prevent over-driving and stripping the screw.
