Caliburn XL screws are professionally engineered fasteners for concrete and similar applications to resist static, wind and seismic, tension and shear loads in cracked and uncracked normal-weight concrete and sand lightweight concrete. Anchors may only be used for redundant applications, where multiple anchors support linear elements (example ductwork) when designed. The aggressive thread pattern creates a track that burrows into concrete and is designed for trapping excessive concrete dust thus keeping the threads sharp. They feature a patented thread design for ease of driving the screw. The Caliburn XL is Climatek coated for high corrosion resistance.
