TorqueMaster masonry screws are designed with heavy duty masonry anchoring applications in mind. Manufactured with hardened alloy steel for maximum strength and coated with a Blue Ruspert coating for superior corrosion resistance, TorqueMaster masonry screws are suitable for both interior and exterior use, as well as use in ACQ treated lumber. The star drive eliminates cam-out, while serrated threads help cut through the pre-drilled hole for a strong hold. The appropriate driver and drill bit are included in each box of TorqueMaster screws.
