Professional Coarse Thread Drywall Screws 4.8x140mm (No.10 x 5 1/2") - Pack of: 20 Black Phosphate Bugle Head

Maximum grip IN timber: Features a deep, aggressive coarse thread specifically designed to bite securely into wooden studs and framework, ensuring high pull-out resistance and a rock-solid fix for heavy plasterboard sheets. Self-countersinking bugle head: The unique curved head shape compresses the gypsum board surface to sit flush or slightly recessed without tearing the outer paper layer, creating the perfect smooth base for taping, filling, and skimming. Corrosion resistant finish: Coated in a durable black phosphate finish, these screws are protected against rust and corrosion, increasing their lifespan and reducing friction for a smoother, faster drive into the material. Sharp piercing point: Engineered with an ultra-sharp needle point for an immediate start, eliminating the need for pre-drilling in most timber and drywall materials, significantly speeding up installation times on large projects. Hardened steel durability: Manufactured from high-grade hardened carbon steel with a Phillips drive recess to prevent cam-out, ensuring these fixings can withstand high torque during installation without snapping or stripping.
