With the Spax universal chipboard screw, you create tight and seamless wood joints with complete confidence. Thanks to the partial thread, chipboard, MDF, and solid wood workpieces are drawn firmly against the wooden substrate without leaving gaps. The countersunk head sinks cleanly into the timber to ensure a neat, flush finish. Featuring a reliable PZ2 Pozidriv drive, driving this 4.5 x 30 mm screw is smooth and controlled without bit slip. The zinc-plated Wirox coating on the hardened steel provides dependable corrosion protection for furniture making and indoor timber projects, giving you maximum control and lasting results on every fixing.
