 823 Series Sets (1-1/2
- 12") and 823M Series Sets (40 - 300 mm)
The Starrett 823 Series Tubular Inside Micrometers are highly useful tools for internal linear measurements such as measuring cylinders, rings, setting calipers, comparing gages, and measuring parallel surfaces.
The extension rods are made of steel tubing, light in weight, yet extremely rigid. Starrett rods are approximately 3/8" (9.5 mm) in diameter to meet the requirements of mechanics who prefer this larger diameter. By removing the hardened and ground
anvil ends (end caps) of the micrometer head, the rods may be attached to either or both ends of the micrometer as preferred. Each rod may be individually adjusted for wear by the hardened and ground anvil at the end.
Each set is furnished in an attractive, protective case with assembly instructions for various measurements
 Tubular Inside Micrometer
Features:
- Starrett Rods are attachable to either one or both ends of the head ensures the best balance, feel and ease of reading
- Designed to have a firmer rotation than regular micrometers. This is to limit the tendency of the micrometer head to rotate when withdrawn from the workpiece.
- All contact points are hardened and ground for better accuracy and long life
- Satin chrome finish on micrometer head and reading surfaces that resist rust and also make for easy reading by providing a no-glare back ground for the sharp lines and figures
- Starrett advanced sleeve design with staggered lines and distinct figures for precise and easy readability
- Tubular measuring rods are lightweight, yet extremely rigid
- Each rod marked with length
- Hardened and ground anvils on rods are adjustable for length. Head anvil is hardened and ground
- Interchangeable anvils on both 1/2" (13 mm) and 1"
(25 mm) heads
- Quick-reading figures - every thousandth numbered on Inch reading tools
- Lock nut furnished on 1" (25 mm) heads
- 5-1/2" (140 mm) long convenient handle is furnished on micrometers and may be clamped where it will provide correct balance and reach
- Starrett workmanship
