Getting things on order for winter and specifying steel hex bolts for attaching my urethane bucket edge. Last year I bought fine thread stainless -- big mistake -- they went together fine and lasted the winter easily, but one seized up during removal and created a couple hours hard labor for me. This year I'm thinking steel with some kind of finish, and using new bolts every year (that suggestion came from somebody here). There are 5 bolts, and they're 1/2" X 1-3/4". And I'm going with coarse threads to make seizing less likely.
But what finish? Here are my available options for that particular bolt (on McMaster-Carr):
Black Oxide
Black Phosphate
Black Ultra Corrosion Resistant Coated
Cadmium Plated
Hot Dipped Galvanized
Zinc Plated
Zinc Yellow Chromate Plated
Zinc Aluminum Coated
Three other questions:
What material for the hex nuts? Using dissimilar bolt and nut metal is a good way to avoid seizing, but, then, they're likely to see salt and wetness, and dissimilar metals also sets up galvanic corrosion.
And, should I use Locktite?
And, do you like any specials, like flanged heads, or nylon locking inserts?
What say the experienced experts of TBN???
Thank you!
