Starrett 234A-1 End Measuring Rod with Insulated Rubber Handle, 1" Length

The Starrett 234A-1 is a 1" end measuring rod (micrometer standard) designed for checking and setting micrometers of 2" capacity and larger. It is also widely used on machine tools for comparing gauges, checking precision measuring tools, and measuring parallel surfaces.

Key Features:

• Precision construction: Made of special tool steel in rod form with ends hardened and accurately lapped to a spherical radius
• Insulated rubber handle: Minimizes thermal expansion caused by hand heat, ensuring measurement accuracy during extended use
• Comfortable grip: The rubber handle provides a secure, ergonomic hold for ease of use
• Versatile use: Suitable for comparing gauges, verifying precision measuring tools, and measuring parallel surfaces
• 1/4" diameter rod body with spherical ends for reliable contact geometry
• These standards are the same type used on micrometers furnished with standards from the factory

The Starrett 234A-1 is part of the trusted Starrett 234 series, manufactured in the USA to the exacting quality standards that have made Starrett a benchmark in precision measurement since 1880.
