Ball-headed farmer's screw with torx grip provides a better grip. The low head makes the installation look neater and rainwater runs off more easily. The rubber washer prevents water from leaking into the installation.
CE-marked professional screw.
Farmer's screw Kullrig is used to fasten profiled wooden sheets in roof and wall installations. The round head gives a neat end result. Install the screw in the valley of the profiled sheet.
