Timco Countersunk Ribbed Window Screws, 4.3x25mm, 1000 Pack
1000-pack Timco countersunk ribbed window screws (4.3x25mm) - carbon steel with corrosion-resistant zinc & yellow finish.
Timco Countersunk Ribbed Window Screws are a versatile fastening solution specifically designed for fitting hardware to window and door frames without steel or aluminium reinforcement. The countersunk head features ribs underneath to improve countersinking performance, ensuring a flush and secure fit every time.
Manufactured from high-quality carbon steel with a zinc and yellow finish, these screws offer excellent corrosion resistance and durability. The gimlet point ensures easy penetration, while the single thread provides optimal holding power in wood and other soft materials. The Phillips (PH) recessed head allows for secure driver engagement during installation.
These screws are commonly used by window fabricators and joiners for assembling PVC-U, timber, and composite frames. Their specific design minimises material splitting while maximising grip strength, making them suitable for both new installations and repair work.
