Caliper 20 mm by faster tools model 04-1-0120 — precision measuring caliper 20mm

Caliper 20 mm by faster tools model 04-1-0120 — precision measuring caliper 20mm is a compact vernier-style instrument designed for straightforward measurement of external dimensions up to 20 mm. Intended for basic precision tasks, the caliper delivers quick checks of component sizes and fits. Its lightweight construction and simple scale make it suitable for repeated use in workshops, hobby projects and light industrial environments where small-part measurements are required.

Advantages

The caliper offers easy-to-read graduations and a compact jaw span for accurate external measurements up to 20 mm. Its low weight and balanced design enable comfortable handling during repeated checks. The mechanical construction requires no batteries and provides stable readings in environments where electronic tools may be unnecessary. Its simplicity reduces setup time and supports quick verification of parts and tolerances.

Suitable for

• Measuring external dimensions of small components and parts
• Workshop and hobby projects that require 0–20 mm checks
• Basic quality control and fit verification in light industrial tasks
• Repeated manual measurement where portability is important

Key specifications

• Measuring range: 0–20 mm
• Type: manual vernier caliper for external measurements
• Main use: external dimension measurement
• Construction: lightweight mechanical body with fixed and sliding jaws
• Readability: vernier graduations for direct reading
• Power: mechanical, no battery required

How to use

Place the fixed jaw against one side of the part and slide the movable jaw until it contacts the opposite side, ensuring consistent light pressure to avoid deformation of small or soft components. Read the measurement from the vernier scale by aligning the main scale and vernier graduation lines. For repeat measurements, reset the jaws to zero and confirm the zero position before each series of checks. Keep the caliper clean and free from chips or debris that could affect the sliding action and reading accuracy.

Usage recommendations

For best results, store the caliper in a dry place and avoid exposure to corrosive substances. Verify zero position before use and perform measurements on stable surfaces. Use gentle, consistent pressure when closing the jaws to prevent damage to delicate parts and to maintain measurement repeatability.
