142 CALIPER DIAL TYPE BLACK PLASTIC

Overview

The General Tools 142 Caliper Dial Type Black Plastic (142) is designed for precise metric and fractional measurements across inside, outside, depth, and step dimensions in professional and workshop environments.

Technical Features

• No-glare dial face: Reduces reflective interference under workshop lighting, enabling accurate readings without eye strain.
• 0–150mm (0–6 in.) measuring capacity: Covers a wide range of component sizes suitable for both metric and imperial applications in a single instrument.
• Free-wheeling thumb roller: Allows the slide to be advanced and retracted quickly and smoothly, improving measurement efficiency during repeated use.
• Dual-graduation bar scale (1/16 in. and 10mm): Provides direct-read metric and fractional imperial values without conversion, reducing the risk of reading error.
• Fractional conversion table on back: Offers an on-tool reference for converting measurements, eliminating the need for a separate reference chart in the field.
• Plastic construction: Keeps the tool lightweight and resistant to corrosion in environments where metal calipers may be subject to oxidation or chemical exposure.
• Multi-mode measurement: Capable of inside, outside, depth, and step measurements from a single instrument, reducing the need for multiple gauges.

Applications

• Measuring outside diameters of cylindrical components, fasteners, and stock material.
• Taking inside diameter readings of bores, tubes, and openings up to 150mm.
• Checking depth of slots, holes, and recesses using the integrated depth rod.
• Verifying step dimensions on machined or fabricated parts requiring 0.1mm resolution.
• General shop, hobby, and light manufacturing inspection tasks requiring metric direct-read output.
