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

Description

These 4.5mm x 1-1/4″ double countersunk (CSK) head chipboard screws feature the versatile dual-drive design accepting both Phillips and Square (Robertson) driver bits, giving tradespeople flexibility on the job. The double countersunk head profile sits flush or just below the surface of chipboard, MDF, and particle board, making them ideal for cabinet construction, flat-pack furniture assembly, and shelving installations. The coarse thread pattern is specially optimised for soft engineered timber products, providing superior pull-out resistance compared to standard woodscrews. A black zinc coating provides corrosion protection and a clean, professional appearance. The sharp gimlet point starts easily without splitting, even close to edges. Available in bulk packs for production-line and trade use.
