Hi,

We're interested in producing (in relatively large numbers) 1/4-28 UNF 1/2"
Long screws with a quadruple-start. We're thinking of buying an older
(cam-type) screw machine to dedicate to this part. The question is, can
these cam-type machines (e.g. Acme-Gridley, Brown & Sharpe, etc.) cut screws
with multiple starts?

Thanks in advance,
James
