thread sizes, 4-40

[Mallanaga]

ok... i know that 4-40 is a measure of how close the threads are to each other, but I'm looking around on tower, and i see many things with just the 4-40 designation. so... my question is, will any 4-40 rod fit in a 4-40 threaded end?

thanks.

Yep! Has for me, at least.

good deal, thanks. I'm fitting my revo with these and attatching it with this.

i will be using these for the throttle and the brake, and i just want to make sure it will fit. i'm sure i can make them fit though... onder2:

4 is the diameter and the 40 is threads per inch.

ahhhh. that makes sense. in that case, that rod might be too big to fit, right? i should probably go with these then huh? the ball cup reads "One threaded coupler (3/4" long w/ 3/8"x2-56 threads) (brass)" this is going to be excellent...
