Galvanized bolts? Need 36 carriage bolts, washers and nuts

[ArlyA]

I gave up on hot dipped galvanized X years ago and just go with SS. Seems that stainless fasteners have come down in price over the years. You can even reused them it you like, they do last that long.

I live in Michigan where the water is salt free and shark free.
ACQ treated lumber eats up steel fastners faster than a Bear on steroids but I’ve had good luck with anything ‘Spax’ or green label ‘Simpson’ and I love those Torex star heads.
when restocking my bolt bin for farm use, TSC bulk by the pound grade 5 is my go to source.

TSC by the pound is cheapest. Menards for larger than 3/8 or long bolts, Menards for SS bolts in package of a few. I would probably use galvanized. Might last as long as the wood. If not, replace them, still cheaper that SS.

Remember if this is going to be near salt water that stainless doesn't handle being exposed to chlorides w/o oxygen... even 316 chainplates bedded against a sailboat hull have sudden failed because of this. Hot dipped galvanized is what most of the fishing boats use.

My TSC stopped carrying galvanized, which is too bad, because the price/pound was awesome.

For big projects with bulk orders, now I order from boltdepot.com. Much better pricing than Lowes or Home Depot.

Guys,
Electro plate galvanize is a coating, while hot dip galvanize is a chemical bond. The steel when emerged in zinc under temperature (715F) creates not only a coating (like electroplating) but also a chemically bonded mix between the zinc and steel under the surface plate. The chemical bonded layer is what makes it so much more resistant to rusting.

My wife has that decal on her camper-salt free and shark free-good stuff!

Hot dips seem to all be grade 2. Any otherwise are marked but seem rare vs plated. I once pre-drilled 5/16" x 3 1/2" deep for 'waxed' 3/8" x 3" lags and easily snapped 'em off in treated 4x4 posts with a 7" long, 3/8" drive socket wrench and one hand. We hadda go with plated to find grade 5s otherwise back then.

Stainless rocks, but I'm buying a lot of coated deck screws with 'star' drive anymore. (beats the bejeebers out of Ph2 or square drive, IMO)

btw, marine experience means I won't hesitate to through-bolt, include backing plates, and bed fasteners to keep water & O2 out where appropriate. That said, best Ph2 bit I've found is VA "Ice bit" made for drywall. Its narrow #2 tip won't 'cam' out like wider ones & requires less push to prevent the ol' 'rattle' the bungs-up a screw. Buy 'en in 10-packs at $10 or less. You're welcome.

Now, from one Michigander to another. It’s time to build the tunnel before it’s too late.
Bolt that puppy down……

I sure don't understand why the Line 5 tunnel is a bad thing!
I'll leave it that so it's not political.
