Caliburn™ Concrete screws are professionally engineered fasteners with a patented thread design for ease of driving the screw in pre-drilled concrete and similar applications. Caliburn's uncompromised drraw and pull-out strength make it possible to be used in jobs which previously required an anchor. The screw's aggressive thread design afford it the ability to be removed and reinserted into the same pilot hole numerous times-- without the concern of the fastener breaking or the threads wearing.

Applications

• Ideal for use in anchoring to concrete or wood to concrete applications including basement framing and sheds

Features

• Recessed Star Drive for zero stripping, with 6 points of contact
• Aggressive heavy duty threads lock into concrete and can be removed and reinserted without screw damage
• Countersinking Bugle Head locks wood to concrete for complete installation and effective anchoring
• Climatek™ Coating is AC257 code approved for use in treated lumber
• W-Cut™ creates low torque, smoother drive
• Zip-Tip™ requires no pre-drilling, faster penetration
• Case Hardened Steel for high tensile, torque and shear strength
