GRK 19/64" Caliburn Concrete Screw (25pk)

Caliburn™ Concrete Screws are professionally engineered fasteners with a patented thread design for ease of driving the screw in concrete and similar applications. Caliburn’s uncompromised draw and pull-out strength make it possible to be used in jobs which previously required an anchor. The screws
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.

• Star drive eliminates stripping for improved productivity
• Heavy duty threads lock into concrete and can be removed and reinserted without screw damage
