Product Details

English Whitworth Standard Screw Pitch Gauges and International Metric Standard Screw Pitch Gauges

Screw pitch gauges are among the most useful tools in any mechanics’ tool box. They quickly determine the pitch of various threads. These gauges consist of a substantial steel case with a number of folding leaves at both ends, each leaf having teeth corresponding to a specific pitch, marked on each leaf.
Starrett screw pitch gauges are available in a wide range of sizes with different numbers of leaves in various pitch ranges.

  • 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 screw pitch gauges (except 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 gauges have a special narrow design, permitting checking internal threads in nuts, etc., as well as external threads. Various types of Starrett screw pitch gauges are illustrated on the following pages, with complete specifications
