Whether for interior or exterior use, SPAX screws provide reliable, high-performance fastening solutions for all your construction needs.

What are SPAX-M MDF Screws?

SPAX-M MDF screws are specially designed for working with medium-density fibreboard (MDF), providing precise, splinter-free fastening without the need for pre-drilling. Their unique serrated thread ensures quick penetration and firm hold, while the 4CUT point reduces splitting and improves grip in delicate materials.

Ideal for cabinetry, furniture assembly, and interior construction, SPAX-M screws guarantee professional results by delivering high pull-out resistance, reduced material damage, and a clean, smooth surface finish for MDF applications.
