Hexnuts

Tim's measurements of a bunch of hexnuts from the hardware store.

A quarter-inch nut is not .25 inches in size, of course: it's called 1/4 inch because it fits a bolt that's 0.25 inches in diameter. But how does the weight of a nut depend on this "bolt size"?

In a metric size, by the way, the number after the M is the bolt diameter in mm.

  • size The name of the bolt size
  • boltSize That value in decimal inches
  • W weight (OK, mass) in grams
