Αγκύριο επέκτασης Fischer FBN II 10/20

The Fischer FBN II 10/20 expansion anchor is a cost-efficient steel anchor designed for flexible use in non-cracked concrete. With a long thread and two selectable anchorage depths, this zinc-plated bolt anchor is suitable for stand-off installation, pre-positioned mounting, and push-through installation. The FBN II 10/20 is intended for interior applications such as fixing railings, cable trays and consoles and is supplied in packs of 50 pieces.

Advantages

The standard anchorage depth delivers maximum load-bearing capacity, which can reduce the number of fixing points and the size of anchor plates required. A reduced anchorage depth option shortens drill-hole depth and speeds up installation while increasing flexibility. The long thread compensates for component tolerances and supports stand-off installations. Installation requires relatively few hammer blows and shows minimal torque slippage for easier fitting. A drive-in pin protects the thread from damage and enables faster assembly and disassembly of the attachment.

Suitable for

• Fixing railings in non-cracked concrete
• Mounting cable trays and raceways
• Securing consoles and brackets indoors
• Pre-positioned and push-through anchor installations
• Stand-off installations where component tolerance compensation is needed

How to use

Drill an appropriate 10 mm hole in non-cracked concrete to the required anchorage depth. Clean the hole of dust and position the anchor either pre-positioned or in push-through mode. Insert the anchor, then set it by hammering the drive-in pin or tightening to expand the sleeve against the concrete. For stand-off installations, use the long thread to adjust component spacing before final tightening. Follow the specified anchorage depth and tightening torque from the manufacturer for safe load-bearing performance.

Recommendations

The Fischer FBN II 10/20 is intended for use in non-cracked concrete and for interior applications; select the standard anchorage depth when maximum load capacities are required and the reduced depth when faster installation or shallower drilling is needed. Observe load tables and installation instructions from Fischer for spacing, edge distances and torque values.
