Universal Supermicrometer - Model 501, 504
The definitive bench micrometer, the Universal Supermicrometer (USM), offers the advantage of being two instruments in one, by providing the ability to measure both internal and external parts, gages or standards. Additionally, as a high precision, direct-reading metrology instrument, it is equally capable of checking critical components such as shafts, bores, O-rings, or just about any ID/OD part. The USM digital bench micrometer can serve as both the heart of your in-house gage calibration needs and a high accuracy part inspection system.


The Universal Supermicrometer® measures:

  • Length standards
  • External threads
  • Ball bearings
  • Plugs & pins
  • Plain ring gages
  • Setting Standards (Frames, Rods)
  • Dial, digital and test indicators
  • Gears / Splines
  • Tapered pipe threads / API
  • Your Precision Part
