What is a Ring Nail?
A Ring Nail is the type of finish on a nail, mot commonly found in Coil Nails and Strip Nails. It is a set of grooves within the body of the nail (also known as the shank) to give a more powerful hold in the fixing of materials. Basically, there are grooves on the fastener to allow it to have better holding power after it is inserted into the surface.
This is also sometimes referred to as a 'Ribbon Shank'.
