Spax® Wirox MDF Screws 4.5mm

Clean Fixing. No Splitting. Perfect for MDF.

The SPAX 4.5mm MDF Screw is specifically designed to tackle the challenges of fastening into MDF and other engineered wood products. Whether you’re assembling cabinetry, furniture, or interior fit-outs, this screw delivers clean, reliable performance — with no need for pre-drilling in most cases.

Key Features:

• WIROX Anti-Corrosion Coating

  Long-lasting corrosion resistance, far exceeding standard zinc coatings. Ideal for indoor use or protected outdoor environments like garages or undercover patios.

• Optimised for MDF & Engineered Wood

  The screw geometry is designed to reduce swelling, splitting, or surface bulging in MDF and particleboard, providing a cleaner, tighter hold.

• CUT Point Tip

  The self-starting, sharp-point tip cuts smoothly into material with minimal effort — no pre-drilling required for most MDF panels.

• T-STAR plus Drive

  Allows for stable bit engagement, faster installation, and less slipping. Ideal for high-volume cabinetry and joinery work.

• Partial Thread Design

  Provides high clamping force, drawing the workpieces tightly together for long-lasting joints.

• Countersunk MULTI Head

  Ensures a flush, professional finish in MDF without surface damage. The under-head ribs cut neatly into the surface for a clean seat.
