Mitutoyo 126-903 Screw Thread Micrometer 2 to 3 Inches

Product Description

The MITUTOYO 126-903 is a mechanical screw thread micrometer designed for precision thread measurement in the 2 to 3 inch range. It features a ratchet stop thimble for consistent measuring force and interchangeable anvils that allow the tool to be configured for different thread forms. Graduation is 0.001 inches with an accuracy of 0.0002 inches, making it suitable for close-tolerance work in manufacturing, machining, and inspection environments. The satin chrome finish reduces glare during use. This micrometer is intended for use by machinists, toolmakers, quality control technicians, and precision measurement professionals.

This micrometer is used in applications where external screw thread dimensions must be verified to tight tolerances. Typical use cases include incoming inspection of threaded fasteners, verification of machined threaded components, and shop-floor quality control in production environments. The interchangeable anvil system makes it adaptable across a range of thread types without requiring a separate tool for each application. It is suited for both job shop and production inspection settings where repeatable, accurate thread measurement is required.

Key Features

• Measuring range of 2 to 3 inches for mid-range external thread measurement
• Ratchet stop thimble ensures consistent measuring force across repeated measurements
• Interchangeable anvils included for use across multiple thread forms
• Graduation of 0.001 inches with 0.0002 inch accuracy for close-tolerance inspection
• IP65 ingress protection rating provides resistance to dust and coolant splash
• TUV certified and satin chrome finish; includes plastic storage case

Compatibility

Designed as an OEM-style precision measuring instrument for external screw thread inspection in the 2 to 3 inch measurement range. Compatible with applications requiring interchangeable-anvil thread micrometers of standard spindle diameter 6.35 mm.

Installation Notes

This micrometer requires no installation and is a handheld precision measuring instrument. Calibration should be verified before use according to your facility's metrology procedures. Store in the included plastic case when not in use to protect the measuring faces and anvils. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin contact on precision surfaces.
