Robosource.net is now offering T15 Star Drive motor screws for use with VEX Motors. These screws are pretty much impossible to strip and much more durable (compared to the 5/64" hex drive screws that come with the motors), yet still inexpensive. Uses the same T15 Torx tools as VEX’s 8-32 star drive structure screws and available in both 1/4" and 1/2" length. These are made from 304 Stainless Steel (aka 18-8 Stainless Steel), so they’re just as strong as any regular screw but with a much higher torque head.
