Starrett End Measuring Rod with Rubber Insulating Handle Straight Edge Tool

The Starrett End Measuring Rod with Rubber Insulating Handle is a precision micrometer standard, also called a setting rod or end standard. It is used to check and set micrometers of 2" (50 mm) capacity and larger. Starrett 234 Series rods are also used on machine tools to compare gages and check precision measuring tools. They work well for measuring parallel surfaces and many other inspection and shop tasks.

Key Features:

• Tool steel construction: Each rod is made of special tool steel. The ends are hardened and accurately lapped to a spherical radius.
• Insulating rubber handle: The handle gives a comfortable, secure grip. It also helps limit heat expansion from the heat of your hand, which supports measurement accuracy.
• Spherical end geometry: The ends give consistent contact when you set and verify micrometers.
• Versatile calibration use: The rods are the same type of standards supplied with micrometers that come with standards. They suit micrometer checking, gage comparison and parallel-surface measurement.
• Made by Starrett: Starrett has a long American heritage in precision measuring tools.

The 234 Series is available in a range of lengths and diameters in inch and metric versions. Choose the rod that matches your micrometer capacity. Machinists, toolrooms, inspection departments and calibration labs use these rods to keep measurements accurate and repeatable.
