🔄 Deep Coarse Thread Design

Coarse, deep threads provide superior grip in wood studs, preventing the screw from backing out or loosening as the wood moves or shrinks. Ensures a tight, secure hold for drywall panels.

⚡ Self-Tapping Point

The sharp, self-tapping tip easily penetrates drywall and bites into wood without pre-drilling, allowing for fast, effortless installation.

🧩 Bugle Head (Countersunk)

The flat bugle head sits flush with the drywall surface without tearing the paper, creating a smooth finish ready for taping and joint compound. The Phillips drive provides a secure, non‑slip grip.

🔩 Durable Finish Options

Available in black phosphate (low corrosion resistance, reduced visibility in drywall) or zinc plated (improved corrosion resistance), suitable for a wide range of interior environments.

🏗 High-Strength Construction

Made from high-quality C1022 steel with Class 4.8 or 6.8 strength grades, strong enough to handle heavy use without breaking or stripping. Stainless steel options also available.

📐 Product Knowledge
