About Starrett No. 439 squares

The L.S. Starrett Company is an American precision tool maker based in Athol, Massachusetts, and has been producing measuring tools since the late 19th century. Its reputation rests on squares, calipers, rules and levels made to machinist tolerances, and the sample follows that pattern with combination and bevel squares, dividers, depth micrometer sets and machined rule clamps. Complete sets matter: a No. 445 depth micrometer with all its rods, or a combination square with the full head complement, beats an orphaned blade. Original boxes, crisp graduations, clean nickel or black wrinkle finish and legible trademark stamps all lift an example, while pitting, worn markings and missing accessories pull it down.

The 13 sales behind these figures come from Jim Bode Value Guide (12) and Jim Bode Tools (1), and run from 2020 to 2026; 2 closed in the last twelve months.
