Dual head

• Higher force transfer with hexagonal recess possible - important for particularly hard woods in the refurbishment of old buildings
• Additional customary T-slot (T40)

Screw-in marking

• The friction part serves as a practical marking for the remaining length, which must protrude out from the wood.

Thread

• Coarse thread including patented follower thread, rolled out to the tip
• Faster screwing processes
• Minimised blast effect
• Low screw-in torque

Tip

• 35° tip to drill quickly - especially for 45° pitch
