[Nitroz28]

i bought 10 3x10 mm machined screw button head SS and they dont work in my HPI 15FE . these what hpi recomends 3x10 mm is it b/c its SS or not i dont know i have to go back to lhs tommrow .why dont these work ?

arent there different types of threads for screws? i guess you might have gotten the wrong one?

most r/cs use the machined screws(the tightly packed together threaded screws. then there are what u call wood screws that are spaced out more and more of a spiral. correct me if I'm wrong.

yes you right, but i believe there are different types of threads for machine screws...ex 10-32 is different from 10-24

man i pushed the button too early, i believe 10-32 and 10-24 can be the same length and diameter its just the different thread....go to lowes or ace i think youll understand what I'm sayin

o cool it added it to my other post!

they are to big i have to screw them into the head making new threads in the head. and the same thing in the case they are just slighty to wide.

First number such as the 10 in 10-32 is the diameter of the threaded part of the screw. The second number such as the 32 is the number of threads per inch.

yeah so you could get a 10-28 instead of a 10-32 and itd be the same diameter but not fit?
