Dale, When your working on 7,8,10mm 1.0 pitch fine threads it doesn't take a lot of tightening to strip a thread. Some people when working on cars screw thing s down till the aluminum wants to strip out the threads. Just tighten them down snug. There are rubber O-rings on them so they don't have to be torque to 5, 10 or so LB's. Just tight. John Hervey www.specialTauto.com << I'm even more confused about this than you. Does this mean open them all the way then turn them "lightly". Is lightly a quarter turn or a half turn or a full turn? Does closed lightly mean they should be nearly all the way closed then barely not closed? Dale Funk vin 4984 >>
