How to cut machine screws?

[pete2222]

Hi All

I just wondered if people cut their machine screws down to the desired length, or always just buy ones of the correct length.

For example, I have plenty of 10mm M3 cap screws, but need some 6mm. I've seen a website showing that this can be done using electricians pliers. However, are there any better methods. Is the finish on the end good enough not to wreck the threads in an expensive motor.

Thanks
