A feeler gauge set consists of several blades of various thicknesses with measurements marked on each piece. While these thin “blades” do not include any sharp edges, they are designed to be slid into gaps to see exactly how wide they are. Obviously, this is used for smaller openings that can be difficult to measure accurately. With the feeler gauge set, you can just simply slide in the blades one at a time until you find the exact width of the gap. Then, you can continue on with your project, confident that your measurements are precise.

Whether you’re using the set to measure valve tolerances, bolt gaps, or to make other critical measurements, the 32 Piece Feeler Gauge Set will feel things out for you to an exact degree! And for just $3.99 for the entire set, you’ll feel just fine adding this measuring tool set to your workspace.

“I bought this feeler gauge set to measure the bolt gap on my PTR-91 (G3 pattern) rifle. I measured each of the plates with my digital calipers and they are 100% accurate measurements at least down to a ten-thousandth of an inch. They are accurate enough for firearms work, so they are accurate enough for nearly anything. I’m glad I saved the money getting this set rather than going and buying one for three times the cost at the auto parts store.” – by Pazuzu from TX

“These are great gauges. They come with a lot of thicknesses and I have yet to run into one it does not have. Some of the other ones I’ve used don’t get small enough for my motorcycle’s valves (.002 inch) but these do. It does come with a very light coating of a thin oil most likely for an anti-rust coating or to help with moving the arms. If it annoys anyone, it is very easily wiped off.” – by ct from CT

These steel blades are a great addition to any work space and feature both Metric and SAE measurements. And they come in a convenient, compact size that fits easily into your pocket or any tool bag.
