Our M10 Bolt Screws are designed to work specifically with any copper or steel downspout hanger that requires an M10 thread for attachment to the component. The “business” end of the screws features a wood point and 3″ of thread for mounting in just about any location, including stone and concrete. Pre-drilling is suggested in wood products and required in stone and concrete.
We offer this screw in a 4″ length with an option of either copper or yellow-zinc (galvanized) steel coated.
NOTE: If you are purchasing our downspout hangers, you can select hangers with the screw option of your choice.
