Leaf Feeler Gauge Forsage F-61802 — 26 Blades 0.04–1.00 mm

Feeler (leaf) gauge Forsage F-61802 — 26 Blades 0.04–1.00 mm is a compact folding set of precision blades designed to measure clearances, gaps and tolerances in engines, mechanical assemblies and fitted components. The set includes 26 individual blades with thicknesses from 0.04 mm up to 1.00 mm, each clearly marked for fast identification. Its folding design protects blades during transport and allows convenient on-site measurements for automotive repair, industrial maintenance and precision fitting tasks.

Advantages

The set provides a wide thickness range in a single tool, enabling accurate measurement of small and medium gaps. Individual blades are laser-marked for easy selection and return, while the folding holder keeps blades aligned and protected. Constructed from hardened steel, the blades maintain shape and accuracy under repeated use. The compact format is suitable for workshop toolboxes and field service kits, offering both portability and durability without sacrificing measurement clarity.

Suitable for

• Adjusting valve clearances and ignition timing in internal combustion engines
• Checking bearing play, shaft end-float and gear backlash
• Measuring gaps in assembly, sheet metal fittings and machine components
• Precision fitting and calibration in maintenance and repair operations

Key specifications

• Number of blades: 26
• Blade thickness range: 0.04 mm to 1.00 mm
• Blade material: hardened steel
• Blade marking: thickness marked on each blade
• Design: folding holder for compact storage

How to use

Select the blade corresponding to the expected clearance and insert it gently into the gap to be measured. The correct blade should slide in with slight friction; if it fits too loosely, choose a thicker blade, and if it will not enter, select a thinner blade. For precise readings, ensure mating surfaces are clean and free of debris or oil that could alter fit. After measurement, return the blade to the folding holder to protect edges and maintain calibration.

Usage recommendations

Store the gauge in a dry environment to prevent corrosion, and clean blades with a light solvent and lint-free cloth after use. Avoid bending or prying blades under load; use the appropriate blade thickness for the task to preserve accuracy. Periodically check blades for wear or nicks and replace the set if individual blades lose their flatness or markings become unreadable.
