Arriving late October 2025 for delivery – Pre-order now
Condition: Brand new, still sealed in its original packaging. The instrument is unused. Please note: this set does not include the interchangeable ball anvil or spindle inserts used for measuring thread / gear over-pin diameters — these must be sourced separately.
This Mitutoyo 324-251-30 is a digital gear / thread micrometer (also referred to as a gear tooth micrometer) engineered to measure the over-pin diameter of gear teeth and thread profiles. It is part of Mitutoyo’s Series 324 digital micrometer line. With its digital readout, ratchet stop, and compatibility with various ball-tip insert sets, it’s a versatile tool for precision gear and thread inspection. The unit is rated for resistance to dust and moisture (IP65), making it suitable for workshop environments.
Mitutoyo is a globally respected name in metrology, and their Series 324 gear / thread micrometers are trusted for accuracy, modular design, and durability in industrial settings.
