Outside Micrometer Set, 4-Piece 0–4 in, Hard Case

Outside micrometer set delivers repeatable, ultra-precise inch measurements for machining, metalworking, and engineering inspection. Covering 0–4 in across four micrometers, it helps you verify outside diameters on shafts, pipes, and precision parts with clear sleeve markings, smooth spindle travel, and a ratchet thimble for consistent measuring pressure. Carbide-tipped faces and a locking device support stable readings during checks and setups.

• Measures 0–4 in OD with four machinist micrometers for fast coverage across common shop ranges.


• Delivers high accuracy: ±0.0001 in (0–1 in) and ±0.0002 in (1–4 in) for precise inspection work.


• Improves repeatability with ratchet thimble control and a locking device to hold readings.


• Resists wear using carbide-tipped measuring faces and a rigid metal frame for shop durability.


• Includes hard case, 3 calibration rods, zero-adjust wrench, and instructions for organized storage.

Built for technicians who need dependable inch-only readings without switching units, this precision measuring tool supports daily QC, part fitting, and maintenance checks. Clear graduations help reduce misreads, while smooth spindle action speeds up positioning on parts. Use the included standards and wrench to confirm zero and verify measurement confidence before critical cuts or assemblies. Keep the full kit protected and ready in the fitted case—grab yours today and tighten up your measurement workflow.
