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.
