Fastening washer (P-washer)
The fastening washer is used to fasten the load-bearing elements of the greenhouse. It is designed for usage with beam 40x40 and beam-clips 50x40.
The design of the washer provides a hexagonal groove for the M8 bolt, which makes it possible to significantly simplify and speed up the installation of structures. The side stops of the washer prevent the opening of the beam flanges during installation.
The fastening washer is galvanized, highly corrosion resistant.
