Starrett 53060 Mechanical Inside Micrometer 5 in

Product Description

The STARRETT 53060 is a mechanical inside micrometer designed for precise internal bore and hole measurements. It delivers a graduation of 0.001 inches, allowing technicians to resolve fine dimensional differences with confidence. The head anvil is hardened and ground for durability and measurement accuracy over repeated use. This tool is built for trade professionals who require reliable, repeatable inside measurements during fabrication, maintenance, or quality inspection work. It weighs 0.3 pounds, making it a compact addition to a service kit or toolbox.

The STARRETT 53060 suits applications where accurate internal diameter measurement is required, including pipe fitting verification, bore gauging during HVAC equipment service, plumbing rough-in checks, and general mechanical inspection. It is appropriate for use in both residential and light commercial trade environments. Machinists, pipefitters, HVAC technicians, and plumbers use inside micrometers when verifying bore sizes or checking component fit during installation or maintenance.

Installation Notes

Inside micrometers are used by trained tradespeople and machinists during inspection and fitting procedures. Ensure the measuring surfaces and the bore being measured are clean and free of debris before taking a reading. Calibrate or verify the tool against a known standard before critical measurements. Store the micrometer in its case when not in use to protect the anvil surfaces.
