Questions buyers ask

Can you copy a special nut or stud from a sample?

Yes. MSE makes special nuts and studs to a sample when there is no drawing. It has made piston-rod nuts this way. Send or bring the part and tell us the material if you know it.

Do you cut imperial and DP threads?

Yes. MSE’s centre lathes have thread and feed settings for metric, imperial, module and DP threads. Send the drawing and we confirm on the quote.

Can you cut an internal keyway?

Yes. Internal keyways are cut on MSE’s vertical slotter. Send the drawing and we confirm the size on the quote.
