Looks like you are confusing lty and lwd???

Anyway, both lty and lwd work fine:

  plot(1:10)
  axis(1, lty=2, col="red")
  axis(2, lwd=2)

For sure you mean

par(lwd=0.5)
plot(1:3)

But that won't work on arbitrary devices (AFAIR), because 0.5 is smaller than 1 - and it's hard to draw things that are smaller than one point.

No. If you want to change line widths of stuff within your plot, you don't want to change it for your axes as well.
