79A-6 Starrett (6* / 150mm) Yankee Spring-Type Outside Caliper with Solid Nut and Flat Legs

79A-6
Starrett Yankee Spring-Type Ouside Caliper
solid nut, 6"

Starrett “Yankee” Calipers and Dividers are made from a high-grade
steel and well-finished. The legs are made of flat stock and are very
durable. The fulcrum stud is hardened and has a smooth bearing
surface. The bow spring, although flexible, is exceedingly strong to
assure reliability.
All sizes are available with either spring nut or solid nut. The Starrett
quick-adjusting automatic-closing spring nut is designed for making
fast, positive adjustments. The threads of the nut firmly engage the
screw at the slightest pressure from the leg. When the pressure is
withdrawn, the nut automatically releases itself, sliding freely over the
screw. This feature saves time in opening and closing.
