Method of installation:

1. Before installation select adequate length of screws depending on thickness of elements to be fastened and minimum anchorage depth

2. The fastened wooden elements should be defect-free (no knots, cracks, colourations, rots, structure and shape defects, mechanical damages) as any defects reduce their strength

3. Screws should be installed using screw gun and bit suitable for PZ drive

4. Screws should be driven directly in wooden substrate without prior drilling
