Engineered Performance Advantages

• 1,000-Hour Salt Spray Tested: Multi-layer green organic Ruspert coating exceeds BS EN 9227:2012 standards, completely impervious to the acidic chemicals found in ACQ pressure-treated timber.
• Integrated Flanged Washer Head (8mm Hex Drive): Fixed wide-collar washer head draws timber members tightly together with exceptional pull-through resistance.
• Milled Helix Reamer Shank: Drastically reduces driving resistance, clears bored debris, and prevents friction-induced wood splitting.
• 50° Deep Single Timber Thread: Razor-sharp cutting flute bites instantly into green oak, softwoods, and composite materials for maximum holding strength.
