B-grade Fischer bolt anchor dowel anchor Fbn II 12/250 Gs large washer wood

Scope of delivery

• 10 pieces

Characteristics

• Large contact area thanks to a larger washer – ideal for wooden constructions

• Pre-assembled washer for faster assembly progress

• Standard anchoring depth for maximum load-bearing capacity → fewer fixing points and smaller anchor plates required

• Long thread for compensating component tolerances and standoff mounting → high flexibility

• Easy assembly thanks to fewer hammer blows and minimal tightening slippage.

• The drive-in pin protects the thread from damage → facilitates assembly & disassembly

• The head marking (“W”) allows for easy control of the anchoring.

• Suitable for pre- and through-hole mounting (also conditionally suitable for standoff mounting)

Application

1. Position the hexagonal nut optimally before assembly (the drive pin protrudes approximately 3 mm).

2. When the torque is applied, the conical bolt is pulled into the expansion clip and clamped against the borehole wall.

3. Anchorage can be checked via the head stamp.
