A set of six wood screw with 5/8" thread size constructed of stainless steel/brass with a highly polished nickle plate finish. This construction will not rust or corrode better than the OEM on your Vintage sports car.  Concourse all the way fasteners. Not a cheep steel plated type that will fail over time and better constructed.  These type of fastener are used for many applications  including for use with convertible tops, Tonneau Covers, Carpets, Etc. See my other listings for other fine fasteners.
