Chuck, the 6-32 thread won't be any stronger in brass than in aluminum - in fact most likely weaker. Two benefits to brass as I see it are easier machining and less likely to corrode and seize the thread - the likely culprit if aluminum ones are breaking. What material are they screwed into?

is likely to twist it off, or break the screw slot, when
they guess wrongly that the screw is turned to remove the

Hi Chuck,

Found it. Slight discrepancy though - you mentioned these were made of
brass and the print says 6061 (aluminum). Which is preferable for these?

There is already a blue print for the collets
in the files section of this group.  I have a
copy if you can't find it.
