Fastener Grades.

So I was trying to figure out what M3 fasteners to order at Mr Metric, and fell into the standard state of confusion when offered too many choices I didn't understand.  So, here's the relative price breakdown of a standard piece (or close; I didn't bother to confirm that the M8 piece I randomly selected was available in all the materials).  Sorted by price, with the different sizes marked with ***.  All the items reference standard DIN439B.

Note that Mr Metric has a huge price break at 101 pieces, so be sure and pick that number and not 100.

class              size     type                         price
-----              ----     ----                         -----
STEEL CLASS 4 ZINC M8X1.25  Jam Nut Steel 4 Zinc         .04
STEEL CLASS 8 ZINC M10X1.25 Jam Nut Steel 8 Zinc         .05 ***
STEEL CLASS 8      M7X1.0   Jam Nut Steel 8              .05 ***
BRASS              M10X1.5  Jam Nut Brass                .15 ***
STAINLESS STEEL A2 M8X1.25  Jam Nut Stainless Steel A2   .15
STAINLESS STEEL A4 M8X1.25  Jam Nut Stainless Steel A4   .21
