Philip & Square Drive Single CSK Head Chipboard Screw – 4.5mm x 1-1/4″

Description

The 4.5mm x 1-1/4″ single countersunk chipboard screw combines a traditional single-angle CSK head profile with a dual Phillips/Square drive recess, making it one of the most versatile fasteners in panel and timber construction. The single countersunk head sits flush with the material surface when properly driven, creating a neat, paintable finish suitable for furniture manufacturing, interior joinery, and cabinet making. Its coarse thread is engineered for maximum grip in the fibrous structure of chipboard and MDF, providing strong pull-out resistance even close to edges. The zinc plating protects against rust in typical interior environments. Available in bulk trade packs, these screws are a staple consumable for joiners, cabinet makers, and fit-out contractors.
