The one-sided wood connectors are fixed with bolts which pass through the wood, the tooth plate connector and then through the steel beam that is being connected. After the hole has been drilled into the wood, the tooth plate connector is pressed into the wood. If necessary, use a hydraulic press-in tool.

Approval
The one-sided tooth plate connectors from BB Stanz- und Umformtechnik are subject to the harmonised standard DIN EN 14545

Design:

One side

Advice:

Steel quality
- S 250 GD + Z275
- Yield strength ReH ≥ 250 N/mm²
- Tensile strength Rm ≥ 320 N/mm²
- Breaking elongation A80 ≥ 19 %
- Corrosion protection of 275 g/m² on both sides - corresponds to a zinc layer thickness of approx. 20 μm

Do not use the screw in applications with direct exposure to the weather or in wet rooms with atmospheres containing chlorine gas.
