As described and quality product

Good stuff, will back again thanks

Each different length of screw were in a separate plastic bag. I was looking for screws in a particular length which were part of the kit. So far, they’ve been very useful. Plating seems durable also

I have both SAE and Metric hex sets, neither of which fit properly. Otherwise the screws work well enough.

Love This！！！

I doubt these are 10.9 rated screws. There are no markings on them and the black coating is not black oxide. It seems to be some kind of paint that comes off easily with solvent like a break clean.The screw on the left is standard oxide coated screw and right is a new one not cleaned out of the package.The black on the towel what comes off the screw when cleaning. It should not do that. The only thing that should come off would oil.

These are a pretty good deal for a good screw assortment that come in clearly labeled plastic bags instead of a hard plastic case, which I already have enough of. The major problem with them is they are for sure not 10.9 alloy. There is no 10.9 stamp on the head, and the hex socket *easily* strips and becomes unusable just testing one in a pair of pliers. My fingers are also coated in black stuff after handling them which doesn't happen with any other black oxide screws I have, so I am not so sure about that claim either.These are fine for really light duty applications and if they weren't claimed to be a stronger alloy I'd give them 4 stars, but they are far below specification.

The Allen head strip out with a brand new bit. These are total junk. Do not buy.
