Precision End Measuring Rod 175 mm

The Starrett 234MA-175 is a micrometer setting standard built for metrology professionals and quality engineers who require a certified reference length. Its single 175 mm rod provides a traceable baseline for calibrating micrometers and verifying dimensional accuracy in controlled environments.

Stable Handling and Durable Construction

A bonded rubber handle insulates the 9.5 mm diameter rod from hand heat, limiting thermal expansion during normal use. The solid round profile resists bending and surface wear, so repeated placement against anvils does not degrade the reference face or introduce measurement drift.

Replaces Worn or Uncertified Setting Standards

This rod upgrades workshops relying on improvised gauge blocks or ageing standards that have lost calibration status. The jump is worth it when traceability to a known 175 mm length is required for audit compliance or when existing references show visible end-face damage.

Highlights

  • Micrometer setting standard with 175 mm length
  • 5 mm diameter round end for precise calibration
  • Rubber handle provides secure grip during use
  • Single-piece rod construction ensures consistent accuracy
  • Metric dimension type matches workshop requirements

Questions about this item

How do I install the 9.5 mm Starrett 234MA-175 rod into a micrometer for calibration?

Place the 175 mm rod between the anvil and spindle, then turn the thimble until both faces contact the rod ends without forcing.

What maintenance will the rubber handle and rod surface need over time?

Wipe the 9.5 mm rod and handle with a clean, dry cloth after each use; apply light oil to the rod if it will be stored for long periods.

What limit appears first when the 175 mm standard is used repeatedly in a warm shop?

Thermal expansion of the 9.5 mm rod length will shift the reference point before any mechanical wear becomes measurable.
