Currently I have a few young folks that are interested in learning to work on cars. As part of my knowledge sharing I am working get them to recognize hardware by the size of the threads, not wrenches. Those screws on the drums are 7mm and yes they have an 11mm hex. I think they are they only 7mm screws on out vans from the factory. For most small DIN fasteners the head is thread size + 50% +up to the next size. For the large stuff add 50%.

Eleven millimeters. Yer prol'ly right. Seems every thing is big this morning, including the size of my head and the headache in it! To much Christmas partying last night!
