These are the fine thread, screws that fit the Lucas Magdyno triangular front cover in place, as used on most Norton roadgoing singles from the 1930's through to the late 1950's. Nice shallow curve to the front of the screws, as per the originals. Price is for pack of 4
These are nicely plated steel with the correct slight front curve as the original screws (see the last picture, of an original Lucas Magdyno as fitted to my 1937 Inter for reference)
