What’s the consensus or suggestions for when to use #6 or #8 screws for bottom coil assemblies on new playfields?
Quoted from Ollulanus:Standard design on most pins 80s/90s era I've worked on seems to be #8 for mechs/solenoids, #6 for everything else (lamps, switches, etc ). Seems logical to use heavier screws for stuff that vibrates and such, but I suppose I'm not convinced it's necessary either.
Thank you sir. Much appreciated.
Quoted from vid1900:If you need to know if a #6 or #8 screw is strong enough for your task, easy math in section 7-9:

Figure a cheap #6 screw is 121 pounds in shear and 38 pounds of withdrawal at 3/8" penetration in maple ply... assuming a fresh hole
So does that mean a #6 is sufficient for all under playfield assemblies in fresh new playfield holes?
