Who said anything about a (fine threaded machine bolt) most machine bolts come in NF or NC I do both, drill, tap also put nylocks on as in the picture. Most do not even know that metric bolts the same size say a 4mm come in diff. thread pitch's
why would any one want to re drill and use a motor mount that has already been drilled, all that does is weaken the motor mount.My goodness a new mount cost less than 10 bucks When properly drilled and tapped an Allen headed machine bolt is hard to beat. You want to use wood screws and a screwdriver by all means use them
