Starrett 73 Series Yankee Spring-Type Inside Calipers, 6" Size & Capacity | Flat Legs, Solid Nut, Hardened Fulcrum Stud, Spring Joint Type, 73A-6

High Accuracy and Precision - Spring calipers are excellent tools in providing accurate markings to maintain exact measurements from one workpiece to another. The flexible bow spring is exceedingly strong and reliable.

Wide Variation of Sizes - All sizes are available with either spring nut or solid nut, 4", 6", 8", and 12". This makes it easy to find the size you need for the job at hand.

Labor Saving - The threads of the nut firmly engage the screw at the slightest pressure from the leg and when the pressure is withdrawn, the nut automatically releases itself, sliding freely over the screw.

Allows Fine Adjustments - The Starrett quick-adjusting automatic-closing spring nut is designed to make fast and positive adjustments to ensure quality work in the workplace.

The Standard for Excellence - Proudly made in the USA, Starrett combines over 140 years of American heritage and innovation with globally sourced materials to deliver exceptional quality tools and products.
