Wood construction screw with double thread

TX drive

• Six force application areas (line contact) for strong power transmission


• No driving-out effect (cylindrical shape eliminates cam-out effect) for a long bit service life


• Can be mechanically driven


• Good torque transmission

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


• Usable length corresponds to the entire screw length

Under-head reinforcement

• Optimal tear-off resistance enhances user safety

Double thread

• Compressive forces are not transmitted into the low-strength insulation material


• Can be used in any insulation material


• High extraction resistance

End mill (friction part)

• Less friction on the screw shaft minimises tool damage


• Less power and force required as it functions like a drill bit


• Lower screw-in resistance


• Easy to install long screws

Coarse thread

• Always provides the optimum speed for each screw length


• The thread geometry enables faster screwing in, saving time during processing

Cutting point

• Low splitting forces due to drilling effect


• Reduced splitting tendency of the wood enables edge connection


• Chipping of the wood fibres

High-quality hardened steel

• High breaking torque


• Optimal installation quality

Anti-friction coating

• Easy to screw in with low screwing resistance, reducing the amount of energy and force required
