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

Description

This white/blue zinc version of the 4.5mm x 2-1/4″ double countersunk chipboard screw is ideal where a brighter, more corrosion-resistant finish is preferred over black zinc — particularly in kitchen and bathroom cabinet installations, damp utility areas, or anywhere a cleaner aesthetic is required. The blue-white zinc electroplating provides a higher level of salt-spray resistance compared to standard zinc, making these screws suitable for semi-exposed interior environments. The dual Phillips and Square drive head offers versatility across driver systems, while the double-countersunk profile ensures a flush, professional finish in MDF and chipboard panels. The coarse thread delivers outstanding pull-out resistance in engineered timber products. Supplied in trade-sized bulk packs for cabinetmakers, shopfitters, and building contractors.
