Starrett Screw Pitch Gage
4-84 TPI range

Starrett screw pitch gages are among the
most useful tools in any mechanics’ tool box.
They quickly determine the pitch of various
threads. These gages consist of a substantial
steel case with a number of folding leaves
at both ends, each leaf having teeth
corresponding to a deﬁnite pitch, marked on
each leaf.
Starrett screw pitch gages are available in a
wide range of sizes with different numbers of
leaves in various pitch ranges with which to
gage.
V, Uniﬁed, American National 60º threads
Whitworth Standard 55º threads
International Metric Standard 60º threads

English and metric threads are similar in form,
but English threads are described in threads
per inch and metric threads by the distance
from one crest to the next.
All Starrett screw pitch gages (except 473
and 476, which have a positive stop design)
feature a locking device at both ends of the
case, so leaves can be securely locked in
position for use. Leaves on most gages have
a special narrow design, permitting checking
internal threads in nuts, etc., as well as
external threads.
Various types of Starrett screw pitch gages
are illustrated on the following pages, with
complete speciﬁcations.
