With Spax chipboard screws, you can securely mount hardware, hinges, and thin sheet materials to wood without worrying about corrosion. Crafted from A2 stainless steel, these 3 x 12 mm screws offer dependable rust resistance for outdoor projects and damp indoor environments alike. The full thread design delivers maximum holding power and pull-out resistance across the entire screw length. Driving is smooth and controlled thanks to the t-star plus T10 drive, which prevents bit slippage and cam-out. The countersunk head with brake ribs mills cleanly into the wood, leaving a neat, perfectly flush finish on every job.
