Our Color Zinc Coated Coarse Thread Drywall Screws are engineered specifically for the efficient and reliable installation of gypsum wallboard (drywall) to wood or light-gauge steel studs. Featuring a sharp self-drilling point, aggressive coarse threads, and a durable color zinc coating, these screws are designed to drive quickly, seat flush without tearing the paper face, and hold firmly for a long-lasting finish. The distinctive color coating not only provides excellent corrosion resistance but also allows for easy visual identification during and after installation. This is the essential fastener trusted by professional drywall contractors and DIY enthusiasts for creating smooth, stable walls and ceilings.

Our DIN 935 Hex Castle Nuts (also known as Hex Slotted Nuts) are precision-engineered, single-piece fasteners designed for secure, vibration-resistant connections where reliable mechanical locking is essential.
