Z3 hardtop front screws/bolts

You should be able to source them from any good hardware store, T40 Torx, if my memory serves me right.
 
Lol but seriously any can anyone remove one of theirs and let me know its length? Oh god here we go again.
 
Thread length is around 35mm if I recall correctly. Mine are Allen heads though not Torx as my fitting kit is the aftermarket one. Think they are 5.5mm size Allen key. I will measure one tomorrow.

Looking at realoem they are an M8X18 Torx bolt, but beware they have a countersunk head with a rubber o-ring around them which may act as a seal and also keep them captive when the hardtop is removed. It is probably best seeing if you can pick one up from the dealers, part number is 54218410534. Not a very good photo but they are about 32-35mm in length.

The bolt holes on my one were 8mm standard metric thread.
