The connector comprises a carbon steel screw with hi-low thread (lower part) and hexagonal head (upper part).
It is fixed by dry screwing the screw 70 mm, into a specially made hole in the concrete. The head should protrude by 40 mm. Fixing is completely mechanical, as no resins or chemical additives are required. The tip of the screw has a special heat treatment that allows it to carve the concrete in the best possible way. The connection process is therefore fast, economic and clean.
