These #4 x 1/2″ slotted oval head stainless steel trim screws are correct for any classic DB Aston Martin. These were also used on Jaguar and other British cars. These were used to hold on door panels, kick panels, window trims, etc.
This listing is for a bag of 100 screws which is more than enough to do the typical interior.
These Aston Martins used a special #4 flush trim washer. Aston Martin did not use the more common countersunk washer that sat on top of the surface, but rather the one as pictured that is flush with the surface.
