The nails seem to be normal, I ordered this company for the first time. The widest part of the cone, near the head, is 6 mm; the nail does not sit completely in the perforated fasteners, because there is a 5 mm hole. The “ruffiness” is weak, I don’t know if it will stay in the tree, then I’ll test it, I’ll supplement the review. In general, I nailed the supports of the timber for the floor log onto these nails, everything is fine, the nail sits tightly, not one of them is bent.
