Thread: Grade 5 or 8?

Tweet

I use grade 8 on ALL suspension and steering components. Grade 5 is fine for things that are not under stress, things that your life is not riding on, or some things that have multiple bolts. Examples would be things like intake or exhaust manifold bolts, water pump/ fuel pump bolts (you'll strip the threads out of the heads or block before the bolt breaks) or body mounting bolts (a grade 5 bolt is stronger than the sheet metal or fiberglass it's holding), etc. When in doubt, go grade 8.

I buy most of my bolts at the local ACE Hardware. They have a huge selection and prices are reasonable when compared to Lowe's or Home Depot.

The only places I get away from GR8 are bracket mounting (elect fuel pump, fuel filter, etc..., cable\line mounting clamps, ground studs, etc... These get 18-8 stainless fasteners, should they need to come apart later I don't want to deal with corroded bolts.

Me too. The people there can't figure out why we buy so many bolts by the bagful . I guess they don't see that many $100 bags of bolts going out the door. One guy keeps asking me if I have the robot done yet. Our Ace also has some very wierd stuff, like chromed nuts and lots of stainless fasteners.

thats where i get mine to, and yes a bit cheaper i did the napa thing once, ONCE

I found out its just easier to buy the boxes of bolts at ace as I am always using them for something else around the garage , one of my freinds found out why I don't loan out my engine stand bolts to anyone , as they assortment cost me about $50 ( I use the shouldered die bolts) they dont need washers as the heads and shanks fit into the tubes perfectly , also a company called MSC carrys USA grade 8's in bulk too for a decent price in chrome or black oxide .

we have one like that too. the prices are not bad on the chrome stuff either. the chrome acorn nuts make nice finish items.
