I'm not sure if these bolts are actually titanium but they cleaned my mounting holes on my i-Flight motors, the M3 -Mount holes, I measured with my calipers my drone's frame thickness was 4mm and the mounting base was about 2mm, so I figured they would be perfect as the mounting screws that came with the motors were too long causing a short circuit on the front 2 screws could because they touched The coil. Connection. But when I put them in they went in but when I tightened them they just ripped out a hole and I know it has something to do with the screw because I can't tighten the ones that come as tight as I can and it doesn't remove anything so I'm very disappointed hmm if it's because the bracket is steel and they're supposed to be titanium or something but I would be careful about tightening them because you can't over tighten them , definitely not tight enough, wish I installed my motors before they strip, now I can turn the motor off
