Description
Advantage:
- The international approvals guarantee maximum safety and the best performance. The European Technical Assessment even cover use in earthquake zones (seismic C1 and C2).
- The low profile of the screw head ensures for a discreet fixing.
- The design between the bolt and the sleeve ensures high shear load-bearing capacity. Thus, fewer fixing points are required.
- The optimised geometry intelligently reduces the energy required for assembly.
- The approval regulates the use of hollow drills.
Application Area:
- Staircases
- Consoles
- Steel constructions
- Machines
- Gates
Approved for:
- Concrete C20/25 to C50/60, cracked and non-cracked
Application Notes:
- The FH II is suitable for push-through installation.
- When applying the torque, the cone is pulled into the expansion sleeve and expands it against the drill hole wall.
- The black plastic ring prevents rotation when tightening the anchor, and acts as a crumple zone to take the torque slippage so that the fixture is pulled onto the anchor base.
- Available head shapes for flexible design solutions: Hexagon head (type S) and bolt version with nut and washer (type B).
