Field of Application:

For fastening floorboards to wooden substructures (e.g. securing terraces).
Suitable for hardwood (e.g. Bankirai, Douglas fir).

Advice:

Minimum screw length = clamping force + material thickness + drill tip length + 3 mm.

Advantages:

• Corrosion-resistant installation with A2 stainless steel material.
• No need for separate pre-drilling of wood (preliminary test advisable for hardwoods, depending on condition of the wood, pre-drilling and pre-countersinking may be necessary).
• The grooved shaft prevents the screw from tearing off.
• Easy countersinking with milling pockets.
• Small raised countersunk head for an aesthetically-pleasing look.
