Starrett 724LZ-42 Tubular Bow Type Outside Micrometer Set 36-42" Range

The Starrett 724LZ-42 is a professional-grade tubular bow type outside micrometer set designed for precision measurement of large outside dimensions in the 36" to 42" range. Built for demanding industrial and metrology applications, this micrometer set delivers the accuracy and reliability that Starrett is known for.

Engineered with a hollow tubular frame constructed from special steel and welded to exact design specifications, this micrometer achieves an ideal combination of minimal weight and extreme rigidity. The tubular design also ensures a standard coefficient of thermal expansion, reducing measurement error caused by temperature fluctuations.

Key Features:

• Measuring Range: 36" to 42" with interchangeable anvils in 1" steps
• Graduation: 0.001" for precise, reliable readings
• Included Standards: 37", 39", and 41" setting rods
• Spindle & Anvil Diameter: 0.300" (7.6mm) for greater balance and a larger bearing surface
• Advanced sleeve design with staggered lines and distinct figures for easy, accurate readability
• Large thimble diameter with clearly marked figures for reduced reading errors
• Ring-type knurled lock nut for quick and secure locking of measurement position
• Satin chrome finish on thimble and sleeve resists rust and eliminates glare
• Micro-lapped measuring faces on steel spindle and anvils for high accuracy
• Includes a fitted case for organized storage and protection

The 724LZ-42's interchangeable anvil system makes it well-suited for diversified gaging across a wide measurement range without needing multiple instruments. The balanced frame and thimble design minimize operator fatigue during extended use. Recommended for use in machine shops, quality control departments, and precision manufacturing environments.
