If there is an "A" after the dash, the part is cadmium plated, Type II, Class 3, with a drilled head. If there is NOT an "A" after the dash, the part is Cadmium plated, Type I.

My first order was to see if these were correct length(no grind down to fit) for SU Carburetors Suction Chamber screws,This is my 2nd order of these Fillister Head screws as they are better than stock head diameter and of course Safety Wire Drilled !! Wont use anything else on my Carb Rebuilds !!
1st order to make sure they were correct for my carb rebuilds !! And they are perfect for 60s era SU Carb resto race look !! Thanx
