    Standard feeler gages are made of rolled steel not stainless steel. They'd corrode and rust without a protective coating.

    On the surface you'd think it would be better to make feeler gages from stainless. Contrary to belief stainless is much softer but *tougher (stretching, work-hardening and machining) than steel. If you were to use stainless shim stock it would become inaccurate as far as thickness in no time.

    to keep um from rusting when they rust they get thicker/thiner so when that happens it will throw off your measurment
