25 Blades Stainless Steel Long Feeler Gauge, Metric and Imperial Gap Measuring Tool Width and Thickness Feeler Gage Gauge for Spark Plug, Valve Adjustment Tool, 0.038-1.02mm

This is a very good quality feeler gauge set. Still haven’t double check the thickness with a gauge but out of the box they are just what any technician looking to take precise measurements of hard to reach places needs. Clear thickness markings, pouch is a little flimsy but it keeps the dust and dirt of them none the less.

Needed to check clearance in a restricted area. The narrow width worked perfectly. The width is 3/8 tapering down to 3/16. Thinnest feeler is .0012

It works perfectly

I have to deal with a lot of quality control at my job and having this little tool helps resolve a lot of work that needs to be redone.

these are great gauges. would be a 5 star review if the nut to tighten or loosen the handle were knurled or a wing nut. It can be difficult to loosen the small hex nut with fingers when you want to rotate a specific gauge.

Works great for setting lawnmower coils

Checked with a calibrated micThese are off just a little , very useable but not exactfor general use they probably don't need to be accurate with in .0002

I had to put points in a vintage small engine.Thanks to the narrowed ends of the gauges, I was able to get to the points ,going straight in perpendicular with clearance.
