I know this is a silly question, but I've wondered about this for years and years. My C-MAN feeler gage set starts out with a few leafs that *appear* to be brass -- and then all the rest of them *appear* to be stainless steel. :dunno:

The brass are non magnetic. There are some applications that need them.

No, they're not tarnished so, quit polishing them to look like the other blades. :lol:

Sounds like sombody needs some Brasso :lol_hitti



You also use them to set the flywheel / coil gap on small engines. So the magnets in the fly wheel dont stick to the gauge.

That's exactly what I use my brass .010" for ... you must be psychic. :eek2:

Did you already know a reason why they might appear to be brass?

I have silently wondered this question to myself too. I'm glad someone thought to ask out loud.:thumbup:

they are more malleable or struck easier when produced. an easier metal formula to shape to that specific size and smaller.

steel would proabably be too brittle that thin

Yeah, I silently thought too that if the real thin ones were made of steel it would be like a piece of aluminum foil.
Sure are some interesting discussions that come up on here!

I have a whole set that are brass.Can't remember who made them.I have about ten sets of feeler guages so the manufacturers kind of get blurred.

No one else has had the audacity to ask such a ridiculous question. :D

Must be low quality stainless steel to be magnitic in the first place

So if you ue high quality SS in your guages then you wouldnt need brass ones

Every tool company makes steel feeler gauges that are that thin, and thinner, its just that some sets have the brass ones for the reasons already stated, electronic ignition, small engines, etc.

I have a 12 inch long Proto feeler gauge set that goes down to one and a half thousandths (.0015") and I also have a old 4" Craftsman that goes down to .0015"

I doubt that they are stainless,I have sets from Cornwell,Mac,Snap on,KD,Proto and others.The main reason I have so many sets is because they tend to get rusty if they get wet.

Merk,
There is a very simple explanation for this, and I am surprised that none of you guys have hit on it yet. Here it is:

Most of the leaves were picked in the spring and the brass-looking ones were picked in the fall. Duh.:lol_hitti

I use .001 and .0015 and they are Stainless Steel.
