LBS HARDWOOD · Round head screw for plates
Round head screw for fastening perforated steel plates to timber, engineered for high density hardwoods. A special tip with embossed slit elements allows installation without pre-drilling, with ETA-11/0030 approval for structural applications stressed in any direction relative to the grain.
