1 Errors in Micro Fiches and a refresher on fastener nomenclature Wed Dec 04, 2013 8:45 pm

Hi all,
To start a ?minor? complaint about the online microfiches that we use. I've two bookmarked, MAX BMW and RealOEM. And while refurbishing my wanna be cafe Racer K75 I came upon an anomaly, i.e. difference, between the microfiches and the part in my hand. In the two microfiches cited before, part #4 the stabilizer between the two forks would appear to be bolted to the fork lowers using four bolts which go down through the top of the stabilizer into a ledges on the fork tubes. Except NO! they do not. In reality in the part in my hand the bolts have to go up through the ledges and screw into the stabilizer.
Ok, it's a trivial error and I could probably live with it. But the bolts are entered as "07 11 9 919 979 FILLISTER-HEAD SCREW - M8X25 (to 08/91)". Now my reading of that entry says it's size 8 bolt 25 mm long. Which I have 4 of but they're too long. So question, have I mis-interpretted the bolt size, i.e. length? They screw in just fine but... too long. And is there a standard thread pitch per bolt size? And how does the nomenclature for metric handle different thread pitches? The Wikipedia article is rather confusing.
thanks
