M8-1.25 x 16mm Button Head Hex Socket Cap Screws, Class 10.9 Alloy Steel, Black Oxide Finish, Quantity 25

Rusted very quickly. Even though the description says mild corrosion resistance, they really have zero corrosion resistance. I used them to install rock sliders on a Jeep and within just a couple weeks they were completely rusted on all surfaces. I will be replacing them with a different product.

They're the exact size that I needed after finding a few warped, defective bolts, included in a product I'd just assembled. There were no spare bolts provided either. A couple included bolts had terrible porosity on the bolt head and after replacing them all, I had 4 stripped bolts from the free soft steel hex wrench.I ended up needing 56 total for replacing all of the OEM bolts on an otherwise excellent 5 star creeper seat that I'd bought here on Amazon.I found myself venturing out to find the nearest local store at the above mentioned price. That would've cost me $36.40 plus tax if I had purchased all of them locally, which I couldn't because they only had less than 20 in stock. The savings rock!

What i received was painted not black oxide. I also doubt the 10.9 grading. Will find another use for them after running bolts through a die ; the threads look terrible

Perfect fit, right on the money. I opened a propane fire pit table that i had gotten for super cheap at a big box store only to find out that there was no hardware. I didn’t want to return it and lose the deal so I read the instructions and found out that it only took one type of screw to put it all together. These are a lifesaver and I’m enjoying my table now.

I have a Rigid 13" planer that had some bolts with stripped heads. These fit exactly like the originals, and now all of my bolts are fresh and easy to remove when blades need to be flipped!

The product picture is obviously EG, but the one I received is HKP, picture one, the left is the purchase, the right is my original EG, the EG is well made and the lettering is clear. The HKP issued by the merchants is not clear even for 10.9. The quality has not been tested, but it is not satisfied, the picture does not match the actual product, so it can only be returned.

Ordered a high performance part for my WRX STI, a strut tower brace from Perrin. It came with really cheap screws and when I tightened them the heads stripped off.Ordered these screws and no matter what, they held strong. Virtually impossible to strip them. Thank You to whoever sold them to me. Your a life saver.

Just from residual humidity in the FL air (no rain, or direct water contact) surface rust spots are already forming after 1 week of installing.

I had bought a new patio set, but while in a hurry: I had throw away the box with the screw. This were a perfect match

Don't buy this if you intend to wall mount a small Samsung TV. Get a 22mm instead.
