Drill-Stop

Countersinking for deck screws

For Terrassotec Ø 5 and 5.5 mm, Hapatec Ø 5 mm and Hapatec Heli Ø 5 mm
Pilot drilling is strongly recommended for fastening tropical woods/hardwoods. This is advisable even with the relatively easily splittable Douglas fir, and when screwing close to wood cut against the grain.

• Boring and countersinking in a single pass
• Screwing torque for inserting Terrassotec and Hapatec screws is greatly reduced, ie no more shearing of the screws, above all with the combination
• Perfect seat of the screw head
