• Meets BPIR regulation
• 316 stainless
• Star drive allows for greater torque.
• Heads look uniform across screws, unlike Square Drive heads which need to be lined up to achieve a uniform look.
• Pre-drilling generally not required depending on timber and driver (except on board ends).
• Timber is protected from tearing or splitting by the drill tip.
• The self-drilling tip makes the installation quick and easy.
• Small head diameter ensures that the head can sink in cleanly and easily.
• Grooved shank adds extreme holding-down strength.
• Available with three different finishes A) stainless, B) silicone bronze vintage, and C) black coated.
• Smooth head for a perfect barefoot proof finish.

Applications

• Commonly used for hardwood up to 21mm thick and also composite decking
• Decking and cladding to timber substructures.
• Designed especially for hardwood usage.
• Tips for use:
• Use T20 Max Torsion tip to drive screw.

Building Materials

• Merbau
• Spotted Gum
• Blackbutt
• Tallowwood
• Stringybark
• Karri
• Sydney Bluegum
• Jarrah
• Ironbark
• Tasmanian Oak
• Victorian Ash
• Grey Box

Note: Stainless steel fasteners embedded in some high tannin timbers such as Garapa may cause localised tannin stains on the surface of the timber. This risk is reduced by using 316 stainless steel screws (and not 304 stainless steel) and using un-coloured screws (not bronze or black stainless steel options).

Bronze finish is a 'vintage' look and may wear off when installed in high traffic areas, cleaned with abrasive methods or damaged during installation.

Functionality

• Use T20 Max Torsion tip to drive screw.
• SIT® Drive Head: Ensures optimal torque, fast centering, and a snug fit.
• Aggressive Shank: Provides strong grip with reduced drive-in torque—ideal for hardwood without snapping.
• Asymmetrical Thread: Lowers setting torque for easier installation and up to 30% faster screwing with anti-friction coating.
• Pyramid Tip: Minimises timber splitting and speeds up drilling—perfect for hardwood decking and cladding.
• 316 Stainless Steel: Offering high corrosion resistance to reduce the chance of tea-staining and rust, increased fracture torque, and suitability for outdoor and close to water applications.

For best results, we recommend pre-drilling and pre-countersinking holes.

Pre-drilling may be necessary in extremely hard timbers.

Stainless steel fasteners embedded in high-tannin timbers such as Garapa may cause localised tannin staining on the timber surface. This risk is reduced by using 316 stainless steel screws (rather than 304) and un-coloured screws (rather than bronze or black stainless steel options).

Bronze finish provides a ‘vintage’ look and may wear off in high-traffic areas, with abrasive cleaning, or if damaged during installation.
