Replace with Grade 8 bolts of the same size and thread pitch, use anti-seize on them. You don't want to use stainless steel on bumpers, they won't rust, as fast, but they do not have the shear strength that Grade 8 bolts do, 15,000# for a 1/2" bolt. NAPA is an excellent source for Grade 8 bolts.So to reopen an old thread, I found that the 1.5*0.5-13 bolt did fit but the choices at Home Depot were zinc or galvanized, no stainless steel. Also, I have no idea if they're grade 8 bolts. So my question is what material should I be looking for here? The bumper I'm planning on ordering is a Westin 42-2005 Trailblazer Series Black Winch Mount Front Bumper for Wrangler from Amazon. I have a TYGER on the back and this looks like it will go well with it for ca. $80 less.
I should note that the ones I got from TYGER had some sort of black coating.
X2. And don't worry about the gold hex head, you'll get used to it. Once I bent one of the grade 8 bolts when the tow hook was pulled hard sideways. It bent really bad but didn't give out.Replace them with 1-1/2 to 2" Long 1/2"-13 UNC Grade 8 Hex head bolts, they'll make life easier later on if you ever need to remove them..
Rattle can takes care of the goldX2. And don't worry about the gold hex head, you'll get used to it.
