Feeler Gauge Beta Tools 1708/8 — metric 0.05–0.5 mm, set of blades

The Feeler Gauge Beta Tools 1708/8 is a compact metric feeler gauge set with blade thicknesses ranging from 0.05 mm to 0.5 mm. It is designed for measuring gap widths and clearances in mechanical assemblies, engines, and precision adjustments where small, accurate measurements are required. The folding design keeps individual blades organized and protected, allowing easy selection and storage in a workshop or toolbox.

Advantages

This feeler gauge set provides a wide range of thin metric blades for incremental measurement steps between 0.05 mm and 0.5 mm, enabling precise gap assessment. The blades fold into a protective handle to reduce wear and simplify transport. Blades are manufactured to consistent thickness tolerances suitable for routine maintenance and setup tasks, and the tool’s compact size supports convenient use in confined spaces.

Suitable for

• Measuring valve clearances and ignition gaps in engines
• Checking bearing play and shaft endfloat in machinery
• Setting clearances on precision assemblies and fixtures
• Workshop maintenance and automotive servicing
• Adjusting and inspecting small-gap components in production

Key specifications

• Blade thickness range: 0.05 mm to 0.5 mm
• Metric measurement system
• Number of blades: 8
• Folding handle for blade protection and compact storage
• Material: stainless or tempered steel blades appropriate for feeler gauges
• Suitable for use in confined or hard-to-reach spaces

How to use

Select the blade or combination of blades that correspond to the target gap size and fold the remaining blades into the handle. Insert the selected blade between the surfaces to be measured and slide gently; a light friction fit indicates the correct clearance. For intermediate values, combine two blades by stacking them and checking the combined thickness. After use, wipe blades clean of oil and debris and fold them back into the handle to protect the edges and ensure accurate future measurements.

Usage recommendations

Use the feeler gauge at room temperature and avoid measuring under heavy oil or debris; clean contact surfaces before measuring. Store the tool dry and periodically clean and lightly oil the pivot to prevent corrosion and maintain smooth folding action.
