Frequently Asked Questions

Q: What is a feeler gauge used for?

A: A feeler gauge is a precision measuring tool used to measure small gaps or clearances between two parts. Common uses include checking engine valve clearances, spark plug gaps, brake pad thickness, and other tight-tolerance mechanical adjustments.

Q: How many blades does this feeler gauge include, and what sizes are covered?

A: This feeler gauge set includes 17 blades with measurements ranging from 0.02mm to 1.00mm in metric increments, giving you a comprehensive range for most automotive and mechanical applications.

Q: Is this feeler gauge suitable for engine valve adjustment?

A: Yes! This tool is specifically designed for engine valve clearance adjustment. Simply select the correct blade for your vehicle's specification, insert it between the valve and rocker arm, and adjust until you feel the appropriate resistance (a slight drag).

Q: Are the measurements clearly marked on each blade?

A: Absolutely. Each blade has its measurement clearly etched directly onto the surface, so you can quickly identify the right size without guessing or referring to a chart.
