<Level1>TX drive</Level1>
<ul><Level2>Six force application areas (line contact) for strong power transmission</Level2>
<Level2>No driving-out effect (cylindrical shape eliminates cam-out effect) for a long bit service life</Level2>
<Level2>Can be mechanically driven</Level2>
<Level2>Good torque transmission</Level2></ul>
<Level1>Countersunk head with milling ribs</Level1>
<ul><Level2>Flush-mount countersinking of the screw head creates a perfect finish</Level2>
<Level2>Less power and force required due to easy and clean countersinking of the screw head</Level2>
<Level2>Usable length corresponds to the entire screw length</Level2></ul>
<Level1>Under-head reinforcement</Level1>
<ul><Level2>Optimal tear-off resistance enhances user safety</Level2></ul>
<Level1>Partial thread</Level1>
<ul><Level2>Optimal finish due to tight sealing of the top layer of wood</Level2></ul>
<Level1>End mill (friction part)</Level1>
<ul><Level2>Less friction on the screw shaft minimises tool damage</Level2>
<Level2>Less power and force required as it functions like a drill bit</Level2>
<Level2>Lower screw-in resistance</Level2>
<Level2>Easy to install long screws</Level2></ul>
<Level1>Coarse thread</Level1>
<ul><Level2>Always provides the optimum speed for each screw length</Level2>
<Level2>The thread geometry enables faster screwing in, saving time during processing</Level2></ul>
<Level1>Cutting point</Level1>
<ul><Level2>Low splitting forces due to drilling effect</Level2></ul>
<Level2>Reduced splitting tendency of the wood enables edge connection </Level2>
<Level2>Chipping of the wood fibres </Level2></ul>
The wood construction screw is used primarily for wood/wood connections in structural timber construction (e.g. for on-roof rafter insulation, wooden frame construction, roof truss construction, element construction, prefabricated building, staircase construction, etc.).
In damp rooms and outdoors, non-corrosive materials must be used for mounting (DIN 18360, Section 3.1.4.1).
The user is responsible for design considerations.
Installation must be carried out in accordance with the approval certificate!
