Starrett 68062 Mechanical Outside Micrometer Ratchet Stop

Product Description

The STARRETT 68062 is a mechanical outside micrometer designed for precision linear measurement in machining, fabrication, and inspection applications. It features a ratchet stop thimble that delivers consistent measuring pressure, reducing operator-to-operator variation on repeat measurements. The measuring faces are solid carbide, offering extended wear resistance compared to standard steel faces. With a graduation of 0.01 inches, this micrometer is suited for applications that demand repeatable, high-accuracy dimensional checks. It is installed and operated by machinists, tool-and-die makers, quality control technicians, and precision tradespeople working in metal fabrication or manufacturing environments.

The STARRETT 68062 is used in shop floor, toolroom, and inspection environments where outside diameter, thickness, or linear dimensions of workpieces must be measured accurately. The ratchet stop thimble makes it appropriate for production settings where multiple technicians may use the same tool. The solid carbide measuring faces hold up under repetitive contact with hardened or abrasive workpiece materials. The Starrett internal reference number for this micrometer is 436.1MXRL-125.

Key Features

• Ratchet stop thimble provides consistent, repeatable measuring pressure
• Solid carbide measuring faces resist wear from hardened and abrasive materials
• 0.01 inch graduation for precise dimensional readings
• Accuracy of 0.004 mm supports high-tolerance inspection work
• Non-rotating spindle design reduces surface marking on finished workpieces
• Painted frame finish for corrosion resistance and durability in shop environments

Compatibility

Designed as a standard mechanical outside micrometer for general-purpose precision measurement tasks. Starrett internal reference number 436.1MXRL-125 applies to this unit.

Installation Notes

Micrometers require no installation in the traditional sense but should be calibrated against a known standard before use and stored in their protective case when not in use. Clean measuring faces with a lint-free cloth before each use to prevent measurement error from debris. Avoid overtightening the thimble against the workpiece; use the ratchet stop to apply only the designed measuring force. Periodic calibration by a qualified metrology technician is recommended to maintain measurement accuracy.
