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
Free bit in each screw pack
The Formel F universal screw A2 is used in outdoor applications and is particularly suitable for the processing of garden timber, battens and screens.
The user is responsible for design considerations.
Depending on the surface properties, screw-in tests may be required when using the Formel F universal screw A2 (pre-drilling may be necessary).
