SPAX Wirox T20 T-STR Rear Wall Flange Screws 3.5x30mm (Box of 300)

SPAX Flat Flange Head Screws – For Back Wall Applications

The SPAX Full Thread Flange Head Screw is engineered for secure, high-hold installations in chipboard and plywood back panels—particularly suited to cabinet and furniture construction. With its wide, flat flange head, this screw ensures strong surface clamping without the need for washers, while the WIROX coating offers superior corrosion resistance in indoor environments.

Key Features:

• Flat Flange Head: Provides a broad clamping surface for high pull-through resistance—ideal for securing thin materials like chipboard back walls.

• Full Thread Design: Ensures a strong, consistent grip across the entire screw length for reliable load distribution and holding power.

• T-STAR Plus Drive: Star-shaped drive allows better torque transfer, reduces cam-out, and provides secure bit engagement—even at awkward angles.

• 4CUT Point: Minimises splitting and enables easy, precise insertion without pre-drilling (in most wood types).

• WIROX Coating: Offers high corrosion resistance, outperforming conventional zinc coatings—ideal for dry interior environments.

Applications:
Specially designed for use in furniture and cabinet making—perfect for fixing back panels to frames where a wide clamping head and strong, permanent hold are essential.
