Starrett 68065 Outside Micrometer 0.01 in Graduation

Product Description

The STARRETT 68065 is a mechanical outside micrometer designed for precise linear measurement of external dimensions. It reads to a graduation of 0.01 inches and delivers an accuracy of 0.004 mm, making it a reliable tool for machinists, pipefitters, and precision fabricators who need consistent, repeatable measurements. The thimble features a ratchet stop mechanism that limits applied force and prevents overloading the measuring faces, which are constructed from solid carbide for extended wear resistance. The frame carries a hammertone baked enamel finish for durability in shop environments.

This micrometer is suited for dimensional inspection and quality-control tasks in metalworking, manufacturing, pipe, and mechanical trade applications. It is appropriate for both shop-floor use and bench inspection work where a dependable mechanical readout is preferred over a digital display. The ratchet stop thimble makes it practical for repetitive measurements where consistent seating pressure is critical to accurate readings.

• Solid carbide measuring faces resist wear from repeated use
• Hammertone baked enamel frame finish for shop durability
• Non-rotating spindle design maintains stable contact geometry

Compatibility

Designed as a standard mechanical outside micrometer suitable for general external measurement tasks in machining, fabrication, and mechanical trade applications. Starrett catalog reference number 436.1MXRL-150.

Installation Notes

Outside micrometers are hand tools used by machinists, pipefitters, and precision tradespeople and do not require installation in a mechanical system. Before use, clean the measuring faces and verify zero calibration against a known standard or supplied gauge. Store the micrometer with a small gap between the measuring faces to prevent thermal expansion damage. Do not overtighten the thimble lock or use the tool as a clamp.
