Stainless Steel Feeler Gauge Universal Standard SAE and Metric Offset Valve Thickness Gauge 32-Piece Blade Tool for Measuring Gap Width/Thickness

Needed a spark plug gapper (we USED TO get them for free with the purchase of a box of 8 Champion Spark Plugs - yeah, I'm showing my age). The old circle gapper I had was dropped so many times by both my Son and myself that the dents and chips in the outer gapping ring rendered it useless. I got this to replace the old antiquated gapper I've had in my toolbox for years. This works well. There's a liberal film of oil on the blades and case, so it was rust free (reapply after use to preserve a rust free / accurate set of blade gauges). The price wasn't hateful. It's big enough to use easily, but not so big that it's cumbersome. I'm old so I wish the printing on the blades was bolder / easier to read.... but that's Nature's fault, not the manufacturer. Overall, a good value for the price. Five Stars.

Lots of gauges all clearly marked

Gauge mess up wrongs thickness

This is a good tool. I ordered this to upgrade my older Snap-on set with did not support Metric and only went down to .006. I only have one negative commend to share to Amazon customers that like quality tools . This set is held together by a cheap 4mm .75T screw and HEX nut. It should have a Knurled Thumb Nuts - M4 x .75 8mm Round Knobs in 304 Stainless Steel. When using a feeler gauge you often need this to isolate the leaves during use. How much could addition cost to the vendor to do that? Every quality feeler gauge comes with one of these.

Worked great

This was one of the only ones I could find that went this small. Kinda weird sizes. But presumably that’s cause they are mapping imperial to their metric. But get the job done. Would buy again if needed—but this one will last.

De buena calidad ayuda mucho

These feeler gauges got a little wet... and they RUSTED. So if they are "stainless steel", they are a very poor grade. Also - like two other sets (from two other manufacturers) - they are not all that accurate. If you need accuracy - especially with the thinner gauges - you better check them with a good micrometer before you use them - which is what I did, and then used the thickness values that I measured, not the ones marked on the gauges. Wish I could find a set of feeler gauges that really is accurate.
