Field tested on a portable sawmill and the fit and finish are fine on these nuts
Fit and finish are fine on these nuts. The treads are within specification as I put a Go - No Go gauge on them and the nylon is if a good consistence to hold the screw tight with vibrations from the portable sawmill. They are not the cheapest in the world to purchase but they do a good job and yes, I have field tested these on my Wood-Mizer
