What grade of steel are is this hardware?

Purchased through Amazon, it appears that they are grade 8.8, which I now understand is equivalent to SAE grade 5 (thanks for the clarification, A. Baldwin!!) The nuts have "|8|" stamped on each of them, and the bolts have "8.8" stamped on the heads. The description should specify "Grade 8.8" instead of simply "Grade 8."

I don't know the grade of steel but it is good quality. As a large man 300+lbs there is no flex at all when I step on them. Hope that helps.

These are combat steel hook swords and are a very high grade product. I will be using them for practice only, not combat.

It is chinese steel but by no means of the poorest quality they could find at the bottom of the barrel. It still holds an edge pretty well for the price and doesn't seem to chip at all so far, though it may need a once-over with a sharpener to hone up that factory edge. I am not sure what grade it is but I believe it to be one of the mid to high quality grades of the steel that comes out of china.

The steel is the frame of the shelves. The particle board is included. The shelves don't feel stable until you get it all together. Then it feels like a rock.

I am not 100% but close to it, steel. Magnets stick to them so they are not aluminum.

Don't know grade, but it is definitely a good quality and not cheaply made.

There is a matching tool box that goes on top of this shelf. It made of pretty strong steel, not sure of gauge.

All of the hardware is stainless steel. Nuts and bolts are stainless and are high quality.

No idea what type of steel. Worked just fine for replacement springs on utility trailer. Fulfilled my needs perfectly.

I looked over the web, but could not find the answer. However, I have never seen racks of this quality, so I am assuming that they are some grade of steel since they seem too heavy and stable to be made of aluminum.

Don't know, but the overall quality was excellent so I would suspect metal.

I believe it refers to gauge/weight of the stainless steel.18/10 is a good grade.

Not sure of grade ss but I give it A+. It looks great and is sturdy enough to hold without bowing or bending.

Not sure what you are referring to, but mine is tubular steel and welded flat steel plates. Receiver is square steel. Mated right up to existing frame bolt points. Very nicely constructed. Super easy to install.

It looks like steel to me. I seem to remember something on the tag about rust-proofing, too.

They are standard metal screws: probably stainless, they don't look dull like galvanized hardware. I live in the desert; the screws and wood are holding up quite well.
