SKU CH-8W3C-RKDWC

An 18-inch micrometer setting standard with a 7/16-inch round end and rubber grip

  • 18-inch length provides extended reach for deep measurements
  • 7/16-inch diameter fits standard micrometer setting requirements
  • Round end shape ensures consistent contact on flat surfaces
  • Rubber grip insulates hand from temperature transfer during use
  • Single-piece construction eliminates alignment errors between sections

Precision Setting Standard

The Starrett 234A-18 is an 18 inch end measuring rod with a 7/16 inch diameter round end. It functions as a micrometer setting standard for calibration and inspection tasks. The single piece rod features a rubber grip for secure handling during use.

Build Integration

The rubber grip improves control when positioning the standard between measuring faces. Its 18 inch length suits verification of larger micrometers and depth gauges. The round end shape ensures consistent contact geometry. No additional fixtures are required for basic operation.

Upgrade Context

This rod replaces worn or missing setting standards in inch based workflows. The jump is justified when existing references no longer hold tolerance or when extending measurement range to 18 inches. It does not serve metric calibration needs or multi length sets.
