RE: MT2 shocks screw, and nut
Generally the shock tower screws for the fun factors and NX series are 3x24 Socket head screws. Unfortunately due to the longer screw, if you go off a really big jump and land wrong, it is possible to bend them.
With any RC Car landing a jump wrong at a really high altitude is likely to bend the shock tower screws. This is not a problem isolated with just the Fun Factor/NX series.
