Hardened steel, blue passivated (A3K), combi head, AW drive, end mill, full thread, drill bit tip
Connects the wood instead of splitting it
Advantages
- Ideal for mounting steel elements (predominantly stressed with shear loads) on wood
- Lower number of screws thanks to high resistance to extraction and shear
- Ideal fit in round holes thanks to hexagonal combi head with integrated shank expansion
- Reduced metal formats and wooden cross sections due to very short edge distances (as with pre-drilling)
- Easier joining thanks to permitted positioning holes
- Suitable for universal use thanks to screw-in angle 0°–90°
- Approval for hardwood, KERTO/LVL, cross laminated timber and other wooden materials
- Application in utilisation class 1 and 2 in line with EN 1995:2013
Combi head
- With reinforced shaft neck for high power transmission and a precise fit
AW drive – more power
- Optimum transmission of forces
- Excellent fit, rapid finding, no wobbling
- Screw settles securely, virtually no unscrewing of bit
thread
- Symmetrical full thread for high load-bearing capacity.
- Plastic non-friction coating: Enables easy screwing in and reduces the screw-in torque
Drill tip
- Extremely short permitted edge distances e.g. 3xd - d = 8 mm - 60 mm carrier
- No pre-drilling required
Material
- High-strength steel for high breaking torque
Surface
- Blue passivated, A3K, Cr III, min. 8 µm
Do not use the screw in applications exposed directly to the elements, in humid rooms or in atmospheres containing chlorine gas.
