ttap drive (TX drive with pin)

• Perfect fit of the bit results in a long bit service life


• No wobbling, which enables one-handed operation


• No driving-out effect (cylindrical shape eliminates cam-out effect), which means less force required when screwing in and saves time


• Compatible with TX

Countersunk head with milling ribs

• Flush-mount countersinking of the screw head creates a perfect finish


• Less power and force required due to easy and clean countersinking of the screw head

Under-head reinforcement

• Optimal tear-off resistance enhances user safety

Partial thread

• Very flush top wood layer enables optimal results

Jetting thread (special winding fin) with 40 % thread gradient

• Less power and force required as very easy to screw in


• Safe for the user thanks to optimal anchoring in the wood


• Better screwing effect


• Free rasping with no displacement


• Chip distribution

Cutting point

• Low splitting forces due to drilling effect


• Reduced splitting tendency of the wood enables edge connection


• Chipping of the wood fibres

Sharp tip

• Screw tip (25-30°) enables accurate positioning and extremely fast "biting" of the screw

Anti-friction coating

• Easy to screw in with low screwing resistance, reducing the amount of energy and force required
