HOX full thread, single-start thread

HX drive

• perfect bit fit - resulting in high bit life


• perfect power transmission, thus no damage to the head and the surface (no corrosion)


• no cam-out effect, thus greatly improved working comfort (no wobbling)


• holding effect due to conical geometry (stick effect), which increases productivity by saving processing time


• Standard TX bit can be used (the mentioned advantages of the HX bit are omitted)

HOX head stamping

• user safety due to visible European Technical Assessment when installed

Countersunk head with milling ribs

• flush countersinking of the screw head leads to a perfect processing appearance


• low chip ejection on the surface, which prevents damage to the head and the component surface (no corrosion)


• hardly any damage to coated materials


• lower energy and effort due to easy and clean countersinking of the screw head


• suitable for wood and fittings

Underhead reinforcement

• user safety due to highest resistance against tearing off

Shank cutter (reaming part) (from 80 mm screw length)

• less friction on the screw shank ensures tool-friendly processing


• lower energy and effort as it acts like a drill


• reduction of the driving-in resistance


• easy processing of long screws

Coarse and single-start thread

• always provides the optimal processing speed for every screw length


• up to 40% faster processing


• up to 30% higher pull-out values

30° tip with recessed second thread turn

• low splitting forces due to drilling effect


• reduced splitting tendency in the edge area enables edge area screw connections


• extremely fast "biting" of the screw

High-quality hardened steel

• high breaking torque


• highest processing quality

Sliding coating

• easy and clean driving in


• lower energy and effort
