Premium Members Ramon Engle Posted March 13, 2014 Premium Members Report Share Posted March 13, 2014 Anyone know the size of these threaded holes? I tried a 4/40.......I got 3 good turns. Don't think that's it. 2/56 is too small. Anybody have a clue? Quote Link to comment Share on other sites More sharing options...
Premium Members Tom Wills Posted March 13, 2014 Premium Members Report Share Posted March 13, 2014 If you tried a 4-40 and got three turns in, that's an M3 metric screw. Found that out the hard way myself! Quote Link to comment Share on other sites More sharing options...

Premium Members Kar Wai Ng Posted March 13, 2014 Premium Members Report Share Posted March 13, 2014 It's definitely a M3 screw. 8mm long. 1 Quote Link to comment Share on other sites More sharing options...
