EJOT® SDF KB 14A

Applications

• Installation of metal attachments
• For multiple fastening of non-load-bearing systems according to EAD 330284
• Suitable for the structural fastening of wall cupboards, cladding, metal angle pieces

Properties

• Hexagon head with flange
• Approved for all common building materials
• Reliable hold in problematic building materials thanks to optimised expansion part
• Radial expansion for reliable hold
• Product identification through different sleeve colours
• Double safety lock against torsion for secure installation

Base materials
Approved for

• Cracked concrete
• Non-cracked concrete
• Solid masonry
• Hollow and perforated bricks
• Aerated concrete

Note
For planning, please observe approval ETA-15/0027. For bricks of unknown quality, the load-bearing capacity must be determined through pull-out tests on the structure. When used in concrete, a silicone lubricant paste (e.g. FUCHS CHEMPLEX SI-LK 2) and the use of an impact screwdriver with particularly high torque are recommended
