Starrett 68037 Outside Micrometer Set 3 Piece 0-3 in

Product Description

The STARRETT 68037 is a 3-piece mechanical outside micrometer set covering a measurement range of 0 to 3 inches. Each micrometer features a ratchet stop thimble for consistent, repeatable measuring pressure and solid carbide measuring faces for long-term wear resistance. The satin chrome finish reduces glare during use. This set is designed for machinists, tool-and-die technicians, pipefitters, and precision tradespeople who require accurate outside diameter and thickness measurements on metal, plastic, or composite workpieces.

This set is suited for use in machine shops, fabrication facilities, and maintenance environments where outside diameter measurements across three inch ranges are routinely required. The 3-piece configuration covers 0 to 1 inch, 1 to 2 inches, and 2 to 3 inches, allowing a single set to handle a broad range of workpiece sizes without switching tools. A fitted carrying case is included for storage and transport between job sites or workstations.

Key Features

• 3-piece set covers 0 to 3 inches total measurement range in 1-inch increments
• Ratchet stop thimble ensures consistent measuring pressure for repeatable readings
• Solid carbide measuring faces resist wear during high-frequency use
• Satin chrome finish minimizes surface glare under shop lighting
• Includes fitted carrying case for organized storage and job-site transport
• Non-rotating spindle design prevents workpiece marring during measurement

Compatibility

Designed as a general-purpose outside micrometer set for precision measurement applications in machine shop, fabrication, and industrial maintenance settings.

Installation Notes

Outside micrometers require no installation but should be calibrated against a known standard before use, especially after transport. Clean the measuring faces with a lint-free cloth before each use to prevent debris from affecting readings. Store in the included case when not in use to protect the measuring faces and thimble mechanism from damage.
