Samac 4.2 x 75mm Black Phosphate Coarse Thread Drywall Screws (Box of 200)

Looking for strong and reliable drywall screws for plasterboard installation? Samac Black Phosphate Coarse Thread Drywall Screws are designed to provide a secure and professional finish when fixing plasterboard to timber studwork.

Manufactured from hardened carbon steel (C10-18) and finished with a durable black phosphate coating, these screws are built to last. The bugle head design allows the screw to sit flush with the plasterboard surface without the need for countersinking, reducing the risk of damage.

With a 25° super sharp point and twin coarse threads, these drywall screws drive quickly and efficiently into timber or light metal studding – no pre-drilling required. The coarse thread offers excellent pull-out strength, making them the ideal choice for secure plasterboard fixing.

Key Features of Samac Black Phosphate Coarse Thread Drywall Screws:

• Black phosphate finish for durability and corrosion resistance


• 25° super sharp point for easy penetration


• Bugle head to minimise surface damage
