What It Is / How It Works

This feeler gauge is a set of 17 metric blades, from 0.02mm (0.001 in) to 1.00mm (0.04 in), made with high precision steel processing.

Feeler gauges are used to measure small gaps between parts, such as valve clearance in an engine.

Who It's For / Use Cases

Feeler gauges suit mechanics, hobbyists and home garage workers who need to check or set small clearances between metal parts. They are a common choice for engine valve adjustment, where a blade of the right thickness is slid into a gap to read the clearance. Anyone who measures gaps by hand will find a set with a wide range of blade sizes useful.

How to Use / Care

1. Tighten the tensioning screw to lock the blade in use.

How to Choose

Choose a feeler gauge by the gap sizes you need to measure. This set's blades run from 0.02mm (0.001 in) to 1.00mm (0.04 in), so it covers both fine and coarse clearances. Pick the thinnest blade that fits the gap for a closer reading, and move up in thickness until the blade meets resistance.

How is a blade held in place?
A tensioning screw locks the blade in use, so it stays put while you check a gap.

How thick is the thickest blade?
The 1.00mm (0.04 in) blade measures 1 mm (0.04 in).
