I did go and use another set of allen wrenches and it had the same problem as the one that was included with the kit. I measured the screw length and its about a 3x7or8 when in the instruction manual it says 3x10. I found a 3x10 screw and it fit the 2 allen wrench perfect, whith the screw that were with the sand guards however there is a little play when the allen wrench is inserted. I might just use 3x10s from the spare screw bag I ordered today and just sand the ends off when I install them into the guards.
UPDATE: One of the screws just stripped out I had to get a precision allen wrench to get it out, now I need to get either the 3x10 from the bag or see if there is a 3x7 that comes in the bag. Savage i think you were right, I tried to see if the other 3 screws had the same problem with another allen wrench and none of them do, so I believe the culprit of the screw stripping was the allen wrench from the kit. There is a second screw on the same path as the first but not as bad, I might also change that screw out also. Besides that the kit is coming along very well
