• 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

• Designed especially for hardwood usage.
• Tips for use:
• Use T20 Max Torsion tip to drive screw.

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.

For highly corrosive environments, we recommend the use of the 316 Stainless Steel coloured screw only (not vintage or black coated).
