Description
The MITUTOYO 126-142 is a mechanical screw thread micrometer designed to measure thread pitch diameters in the 5 to 6 inch range. It uses interchangeable anvils to accommodate different thread forms, allowing a single tool to cover a variety of thread profiles on the bench or in the field. Graduation is 0.001 inches with an accuracy of 0.00025 inches, making it suitable for precision thread inspection work. The ratchet stop thimble delivers consistent measuring force, reducing operator-to-operator variation. A satin chrome finish reduces glare and resists corrosion during regular shop use. The tool carries an IP65 ingress protection rating and is TUV Certified.
The 126-142 is used in precision machining, toolroom, and quality-control environments where external thread dimensions must be verified against specification. It is appropriate for inspecting larger-diameter fasteners, threaded rod, and machined components with a 0.5 mm thread pitch. Both job-shop machinists and metrology technicians install and use this instrument. Data output capability supports integration with SPC data collection systems when connected to compatible equipment.
Key Features
- 5 to 6 inch measuring range for large-diameter threaded components
- Ratchet stop thimble for repeatable, consistent measuring force
- Interchangeable anvils to accommodate multiple thread forms
- 0.001 inch graduation with 0.00025 inch accuracy
- IP65 ingress protection rating for use in coolant-present environments
- Data output port for SPC or digital readout integration
- TUV Certified to recognized measurement standards
Compatibility
Designed for use with interchangeable thread micrometer anvil sets compatible with the MITUTOYO 126-series screw thread micrometer platform. Specific compatible anvil sets should be confirmed through MITUTOYO documentation.
Installation Notes
Screw thread micrometers are precision measuring instruments and do not require mechanical installation. Prior to use, verify anvil seating and perform a standard calibration check against a known reference. Store the instrument in the included plastic case when not in use to protect the measuring faces and spindle. Calibration intervals should follow your shop quality plan or applicable ISO or ASME measurement standards.
