We have a UMA 16-311-203D airspeed indicator (the 3 1/8" UMA from Van's) and need to replace one of the four phillips pan-head SS mounting screws. Is there a standard size for these? And which nylon lock nut would go with it?
The A&P who's been helping me also mentioned a grasshopper nut as an alternative. Is there one of these that might work?
