FAQ
What is a ring shank nail?
A nail with concentric rings on the shank that lock into the wood for far more pull-out resistance than a smooth nail.
Ring shank vs screw shank nail?
Ring shanks resist pull-out; screw (spiral) shanks twist into the wood as they are driven, holding in dense and seasoned lumber.
