I did do just as you had said we did expand .002-.005 over relaxed fit and machined clamps so part would just slide over them then released them and we also did use a cordless drill and minimum torque setting we at first did use a straight hex key but then changed to the ball end witch did help but still had lots of problems with the screws. The first screws we got with the clamps the hex was so far off center it was just about breaking through the wall of the screw I called Mitee bite and they did next day me out new screws but them only lasted about a day then i had to order a dozen more. We have designed a new fixture for this part witch is working great so at this time we have done away with those clamps but thanks for the advise.... |
