Mitutoyo 126-141 Screw Thread Micrometer 4 to 5 Inches

Product Description

The MITUTOYO 126-141 is a mechanical screw thread micrometer designed for precision measurement of external thread pitch diameters. It covers a measurement range of 4 to 5 inches with a graduation of 0.001 inches and an accuracy of 0.00025 inches. The ratchet stop thimble delivers consistent measuring force, reducing operator-to-operator variation on the shop floor or in the field. The satin chrome finish minimizes glare and resists corrosion in typical shop environments. This instrument is used by machinists, quality control technicians, and precision tool professionals who need reliable, repeatable thread measurement without a digital readout.

The 126-141 is suited for inspecting large-diameter threaded fasteners, threaded shafts, and precision machined components in manufacturing and industrial maintenance settings. The interchangeable anvil design allows the micrometer to accommodate different thread pitches. A data output capability supports integration with statistical process control systems or measurement recording equipment. The included plastic case protects the instrument during storage and transport.

Key Features

• Measurement range: 4 to 5 inches with 0.001 inch graduation
• Accuracy of 0.00025 inches for tight-tolerance thread inspection
• Ratchet stop thimble for consistent, repeatable measuring force
• Interchangeable anvils to accommodate varying thread pitches
• Data output port for SPC or measurement system integration
• IP65 ingress protection rating for use in wet or dusty shop environments
• TUV certified; satin chrome finish reduces glare and corrosion

Compatibility

Designed as an OEM-style precision instrument for use with standard interchangeable screw thread micrometer anvil sets compatible with the 4 to 5 inch range class of MITUTOYO mechanical thread micrometers. Specific anvil compatibility should be verified against the anvil set documentation.

Installation Notes

This instrument requires no installation. A qualified machinist or metrologist should calibrate the micrometer against a known standard before first use and at regular intervals per shop quality procedures. Store in the included plastic case when not in use to protect the measuring faces and anvils. Do not over-tighten the thimble; always use the ratchet stop to apply measuring force.
