Just what is the difference between a 1/4 20 screw and a 1/4 in coarse screw?
I was looking for some 1/4 20 2 1/2 inch nylon screws for my wing hold downs
and couldn`t find any at the hobby shop or any of the building supply places.
I did find one 1/4 coarse at Home Depot and guess what, it seems to work good
in the 1/4 20 threads in the wood blocks.
