( MASONARY SCREW )
Concrete screw is a hardened screw that has a sharp tooth structure, advances by threading itself into a pre-drilled hole, and allows fixing to concrete and similar materials without the need for dowels. Concrete screws are used to fasten materials into concrete, brick or block.
Upon request, surface coating applications such as electro galvanization, zinc nickel, phosphate (black), hot dip galvanization and dacromet/geomet are made.
