Special self-perforating tip with serrated thread (SAW tip) that cuts the timber grains, facilitating initial grip and subsequent pull-through.

The flange head serves as washer and ensures high head strength and pull-through. Ideal in the presence of wind or variations in timber dimensions.

Greater thread length (60%) to ensure superb joint closure and great versatility.

Optimised geometry for maximum performance on the most common construction timbers.
