Hi Jonas,

Being a Lucas product my bet is that it is a British Association thread (BA). 

Based upon Steve measurements it looks like it would be 4BA for which the specs are:

Pitch 0.6600mm

Depth of thread. 0.395 mm

Major diameter 3.6 mm

Effective diameter. 3.205mm

Minor diameter. 2.81mm

TPI (approx.) 38.5


May be tough to find a Home Depot!!
