What diameter are the rods that hold the springs on a snow, dozer plow?

I need to stop and pick up some round stock on the way home and I forgot to measure them. Half inch maybe?

Mine is 1/2" diameter by 13-3/8" long.

Mine are half inch diameter as well

Grind a taper on one end makes inserting them much easier....  I switch mine frequently from 2 hole for plowing to 3 hole for scraping.
