With the Spax 5 x 30 mm chipboard screw, you create tight and secure timber joints effortlessly. The partial thread with a 17 mm thread length pulls your top workpiece firmly against the base structure, eliminating unwanted gaps. Featuring a t-star plus T20 drive, it prevents bit slippage and delivers maximum power transfer directly into your workpiece. The countersunk multi-head sinks flush into chipboard, MDF, or solid wood for a clean finish without splitting the timber. Protected by the corrosion-resistant Wirox coating, this 500-piece pack provides the precision and reliability you need to tackle furniture and interior construction tasks with confidence.
