Timco Countersunk Ribbed Window Screws 4.3x40mm, Stainless Steel (1000pk)
High-quality stainless steel window screws with countersunk ribbed heads. Ideal for timber frames & harsh conditions.
The Timco Countersunk Ribbed Window Screws are designed for multiple applications in window fabrication, particularly when fitting hardware to frames without steel or aluminium reinforcement. Made from austenitic stainless steel (A2-304), they offer excellent corrosion resistance, making them ideal for use in damp or coastal environments.
These screws feature a countersunk head with ribs underneath, ensuring improved countersinking and a flush finish. The Phillips (PH) recess provides good torque transmission, while the single thread and gimlet tip enhance grip and reduce the risk of splitting timber.
