Mitutoyo 126-129 Screw Thread Micrometer Interchangeable Tips, 100 to 125 mm

Description

The Mitutoyo 126-129 Screw Thread Micrometer is an analog micrometer designed for measuring the pitch diameter of screw threads with high accuracy over a range of 100 to 125mm. This model belongs to the Mitutoyo Series 126 and is characterized by its use of interchangeable V-anvil and conical spindle tip sets, which are sold separately.

Key features

• Adaptability: Uses easily replaceable tip sets, which can be purchased for different thread pitches and either a 60° (Metric/Unified) or 55° (Whitworth) thread form.
• Direct measurement: Allows for direct reading of the screw's pitch diameter without needing to perform additional calculations.
• Hardened steel: The interchangeable anvils are made from high-grade, hardened, and precision-ground steel for durability and accuracy.
• Analog display: Features a satin chrome-finished thimble and sleeve with a vernier scale for precise, metric measurements.
• Ratchet stop: Ensures constant measuring force is applied to the workpiece, which helps produce consistent and repeatable measurements.
• Spindle lock: A locking mechanism holds the spindle in place once the measurement is taken, preventing movement and preserving the reading.
• Stable frame with heat shield: The micrometer's frame is highly stable, incorporating a heat shield to reduce inaccuracies caused by thermal expansion during extended use.
• Calibration standard: Includes a standard bar for calibrating the tool, which is necessary for sizes over 25mm.
