If starting with NOTHING bolt wise, what do you use? Grade 8/10.9 with washers and thread lock?
I have been hunting for new flange bolts to put on the "externals" of my new engine with little luck. I like the design intent of a flange bolt, eliminating the need for a flat washer that has a tendency to allow bolts to vibrate loose, but finding specialty bolts is impossible - ones that have a stud for mounting additional components to. Things like the EGR solenoid, WG solenoid, ALT/PS brackets at the headers, etc. In those cases, the only thing I can figure to do is install studs that are cut to the required length, nut it, drill out the accessory bracket hole to fit the stud, then set and nut the accessory in place, thread locking all engagement threads. In most of these cases I can't use the stock bolts because I have taller valve covers and TA headers, so stock fasteners are not long enough.
