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
Notice

Do not use the screw in applications exposed directly to the elements, in humid rooms or in atmospheres containing chlorine gas.

  • The requirements of the European Technical Approval must be observed.

  • The load capacity of the transport anchor in conjunction with the ASSYplus FT COMBI screw (dia. 12 mm) must be checked in accordance with the test report/expert report before each transport operation and must be verified separately.
