   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 (e.g. 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.
