i have found you can get all you want of the m4 x .7 pitch philips screws in the exact length you want but i need the m4 x .75 pitch will it affect anything if i tap out to .7 pitch and install the more up to date ?? just curious ( don,t want to weaken the lugs ) but if thats what there using today after my drums were built 1976 then it shoud be ok
