2. Classifications and Relevant Keywords
a) The Three Types of Micrometers Most Common Globally
- Outside Micrometer: Measures the external dimensions of objects. Widely used for shaft diameter, block thickness, etc.
- Inside Micrometer: Specialized for internal dimensions such as hole diameter, groove width.
- Depth Micrometer: Used to measure depths of holes, grooves, and slots.
b) Micrometer Set, Thread Micrometer Set, & Micrometer Standard Set
- Micrometer Set: Typically an assortment (usually outside micrometers) covering varied measuring ranges with calibration standards.
- Thread Micrometer Set: Precision tool designed specifically for measuring external thread pitch diameters, supplied with replaceable anvils for different thread profiles.
- Micrometer Standard Set: Includes fixed-length standards (gauges) to calibrate and verify micrometer accuracy, essential in QC labs.
c) Advanced Types: Granite/Marble Micrometers
Granite and marble micrometers, like the Measuring Micrometer from Storaen (Cangzhou) International Trading Co., are engineered for top-level measurement stability, non-rusting performance, and mechanical durability—making them ideal for harsh or demanding environments.

7. Professional FAQ on Types of Micrometer
Q1: What are the key material options for industrial micrometers?
A: The most common are alloy steel (for general use), carbide-tipped (for wear-resistance), and granite/marble (for ultra-stable, non-rusting performance).
Q2: How do I select between the three types of micrometers?
A: Outside micrometers measure external features (rods, blocks), inside micrometers are for inner diameters (holes), and depth micrometers check the depths of recesses or holes. Choose based on the parameter to be measured.
Q3: What is included in a micrometer set?
A: A standard set includes multiple micrometers of different measurement ranges, adjustment wrench, gauge blocks (standards), usually in a foam-padded case for calibration and measurement tasks.
Q4: What advantages do granite micrometers offer over traditional steel micrometers?
A: Granite micrometers provide much higher dimensional stability, non-magnetization, corrosion-resistance, and better accuracy under temperature and load variance.
Q5: When is a thread micrometer set necessary?
A: When manufacturing or inspecting threaded components where pitch diameter needs high-accuracy verification, especially for passes/fails in QC labs and fastener production.
Q6: How are micrometer standard sets used in calibration?
A: They provide fixed-length certified reference gauges to verify micrometer accuracy before each batch of measurements or routine calibration as per international metrology standards.
Q7: What installation or storage standards apply for high-accuracy micrometers?
A: Store in temperature-stabilized, humidity-controlled environments. Avoid magnetic fields for granite/marble units, calibrate at recommended intervals, and follow ISO/ASTM calibration protocols.
