im like really new to the site and need help i bought a 86 vn750 for 100 bucks and its tore apart and i was wanting to no if the bolts for the seat gas tanks and few other parts is standard or metric i have the service manual but all it says is for instant one bolt i need is for gas tank all it says is 6x20 that is it i never built bike but seems like kewl project so any suggestions and maybe where i can get them for cheap
They're metric. The 6x20 you listed is 6mm thread size, x 20mm long. But you need to know the thread pitch, which on this bike they're mostly 1.0 or 1.5, re-check the manual, it should be listed. Would look like.. M6x20-1.0 or M6x20-1.5 on the store packaging.
The 6x20 must be one of the front tank bolts.
Lowe's or hardware store is usually the best bet to buy new bolts. If in doubt, take an old bolt, they have thread checkers to match them up.
