• Powerful concrete screw with easy construction.
• The rib on the lower surface of the flange reduces the looseness of the concrete screw.
• European technical certification (ETA) assessment applied to cracked and uncracked concrete for European seismic resistance.
• A serrated shape that cuts rapidly into concrete holes.
• Removal of chips is unnecessary for upward and downward construction.
• For downward construction, perforation 3 times deeper than drill diameter.
• Since it is a non-expansion type which secures minimum anchor distance and minimum clearance distance, it can be hit in the corner and concrete is hard to break.
• For installing full screw bolts of inch size W3/8, temporary fixing of building construction equipment, etc.
