Brass Feeler, Plug Gauge, high-Precision Clearance Gauge, Thickness Gauge, Non-Magnetic Copper Feeler, Single Piece Set, 0.03-1.0mm(100 * 13)

Initially I ordered a stainless steel Feeler gauge that was inexpensive only to find that the feeler measurements were all over the place. Not one of them was accurate, and not even close. So I returned it and found this gauge set and ordered it.Since the one I returned was very inaccurate, I tested the Runningfish feeler gauge for its accuracy. Wow! I was very surprised. Almost every single measurement was within 1/1000 mm. The only one that was out more was the .60mm gauge which measured 0.62mm (close enough for my work).This gauge is worth more than the price. I love the brass instead of the stainless steel gauges. Yes, I scratched the 1 mm gauge to make sure it was all brass, and not just brass plated. It is all brass.Be very careful with the .05mm gauge, it is paper thin and can be easily damaged.

These are really great, but I need one as small as 0.015. The smallest one in this kit is 0.050.

The accuracy was off a little. I have been measuring them with micrometers to confirm the measurement. For the price point it's what I expected.

Easy to use on a magneto

While these are definitely brass, be careful. No edge breaking has been performed on them, and they'll have some pretty nasty burrs from the stamping press that was used to cut them from sheet. Over all, they're relatively cheap feeler gauges. high-precision? maybe for automotive, but anything that requires more accuracy is going to be sad once they come in contact with those edges.TlDr: be careful. dont slice your fingers up with the very sharp edges on these.

Worked as hoped. Thanks.

Handy soft holding pouch and hard case storage

Great for setting gap in older electronic distributor
