An ultra light weight metric Phillips crosshead M3 HEX bolt for your drone UAV flight control boards. Australian AU stock. This gives the option to use metal or nylon posts and have this NYLON bolt as the fail-point to save your CPU board from cracking in a crash. Having built a number of MultiWiiCopters ourselves we find that excess weight is a killer. Build them light!
5 x M3*6 Nylon Bolts - black
Do NOT over-tighten with force - safe to use Blue Loctite®
