      Where can I buy 4 millimeter flat head screws that are cross drilled for safety wire or set up for a clip in different lengths?  Need screws for OTK steering wheel with 6 bolts and the ones that came with it are too short to use a angle wedge with Mychron mount.

      And a 1/16” high speed steel drill bit (buy a dozen)

      Make sure you have speed set correctly (apx 4,000 rpm)
      Use some cheap 30 weight motor oil as cutting lube
      Use a drill press if at all possible

      If you want to cut the threaded end, you can make your own jig from a nut.
      Use an old nylock, it helps prevent the bolt from rotating as the cut starts

      Buy extras and practice, it’s a useful skill and will come in handy.
      Buying pre-drilled metric is expensive and can be difficult to find.
      Most pre-drilled are for the aircraft industry with very little metric to choose from.
