Philip & Square Drive Double CSK Head Chipboard Screw Black Zinc – 4.5mm x 2-1/4″

Description

The 4.5mm x 2-1/4″ version of the popular double CSK chipboard screw offers greater fastening depth for thicker panel assemblies, cabinet carcass construction, and structural joinery. The extended length provides excellent holding strength in chipboard and MDF edges where shorter screws may not achieve sufficient thread engagement. The double countersunk head allows the screw to sit perfectly flush with or just below the panel surface, ready for filling or edging. Both Phillips and Square drive recesses are machined into the head, offering maximum versatility across different driver types and tool brands. The black zinc coating is applied for corrosion protection and a sleek, consistent appearance across finished furniture and cabinetry. Sold in trade packs for high-volume production use.
