F-BohrFix® ZB screws
F-BohrFix® screws have been specifically designed for optimal secret-fixing of tongue and groove cladding profiles.
F-BohrFix® ZB has been created by timber engineers to provide a secret-fix solution for “tongue and groove” profiled cladding. The unique shank design allows for fastening close to the edge of the board without the timber splitting. The succeeding cladding board then conceals the neat 3.2mm head of the F-BohrFix® ZB. The result is a securely fixed façade with a clean, fix-free appearance.
Please note: secret fixing is only appropriate in selected profiles and species, please contact our sales team for advice
The F-BohrFix® ZB is available in two dimensions, each offering the same characteristic tensile force values (F1) for both head and thread.
- F-BohrFix® ZB 3.2 × 40mm – secondary component 16mm; tensile force 0.12 kN (head), 0.34 kN (thread)
- F-BohrFix® ZB 3.2 × 50mm – secondary component 16mm; tensile force 0.12 kN (head), 0.34 kN (thread)
