Feeler gauge YATO YT-7223, stainless steel blades 0.05–0.50 mm, length 200 mm

YATO YT-7223 is a feeler gauge set with 14 stainless steel blades spanning thicknesses from 0.05 to 0.50 mm and a total blade length of 200 mm. This compact measuring tool is intended for precise gap measurement, calibration and clearance checking in mechanical, automotive and maintenance applications. The set contains individual blades in incremental sizes for accurate selection and repeated measurement tasks.

Advantages

Stainless steel blades provide corrosion resistance and stable dimensions for reliable measurements. A wide range of blade thicknesses from 0.05 mm to 0.50 mm allows fine adjustment and verification across small clearances. The 200 mm blade length improves reach and handling when accessing tighter or recessed gaps, and individual blades can be selected to combine thicknesses for intermediate values.

Suitable for

• Measuring and setting valve clearances and spark plug gaps in automotive repair
• Checking bearing clearances and shaft endplay in mechanical assemblies
• Calibration and inspection of small gaps in maintenance and repair tasks
• Precision fitting and adjustment in workshops and production lines

How to use

Select the blade or combination of blades that most closely matches the target gap. Insert the blade between the two surfaces to be measured and feel for light resistance; a properly sized blade will slide with slight friction. For combined thicknesses, stack blades and align their ends carefully before insertion. After measurement, wipe blades clean and store them folded or secured to prevent bending and preserve dimensional accuracy.

Usage recommendations

Keep blades free from oil and debris to maintain accuracy. Use gentle, consistent pressure when inserting blades to avoid bending. When measuring critical tolerances, verify readings at multiple points and use temperature-stable conditions to reduce measurement error.
