About This Product
Students use the screw gauge to measure the diameter of a wire, the thickness of a glass plate or a coin, and other small dimensions too fine for a scale or vernier. Reading the main and circular scales together, and allowing for zero error, is a core skill in school physics and in engineering workshops.
Frequently Asked Questions
What is the least count of the screw gauge?
It reads to 0.01 mm over a range of 0 – 25 mm.
Why does it have a ratchet stop?
The ratchet stop applies the same force each time the spindle closes on the object, so readings are consistent.
