73B-4 Starrett (4* / 100mm) Yankee Spring-Type inside Caliper with Quick-Spring Nut and Flat Legs
Product Description
73B-4
Starrett Yankee Spring Type Inside Caliper
Quick Spring Nut
4" Range
  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  withdrawn, the nut automatically releases itself, sliding freely over the 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.
