[DeTomaso] Techno Question: screw and stud size

[Larry Finch]


 Chuck,

The lens attachment screws used for the OEM Ford tail lights, the USA red/red version and the European red/amber version, use M 4 x 25 mm Phillips fillister head machine screws with a pitch of 0.7 mm. 

The fillister head is a somewhat uncommon version. Its close cousins are pan head and cheese head machine bolts, but the fillister head has a smaller diameter.
