perfect fit for Silverado ABS bolts
I stripped the old ones on my 2001 Silverado ABS unit. These replaces this old ones and hopefully will be easier to remove if I ever have to do that again.

Exactly What I Expected
The 304 stainless steel is durable, and the quantity of 30 screws is just right for my project. They work perfectly and have held up well. Great quality and value for the price

Perfect size for monitors
I bought these to be able to mount my monitors to a monitor arm. I must have lost the original screws, but these are a perfect fit for replacements. I like that they have a bit of 'thumb screw' to them so they are easier to manipulate by hand, and the allen head makes them easy to tighten. They fit my monitor screw hoes perfect, hold the monitors securely, and the stainless finish is really nice too. And on top of that, they came in a nice plactic box to keep them together for the next time I need some of them.

NOT compatible with my pedals
Nothing wrong with the product. Bought them to use as pedal pins on Kona WahWah 2's. They are way too big, but they did seem very well made. No fault of the product, just my error in measuring. Only posting here so no one else makes the same error.

I've never been one to get excited about screws, but let me tell you, these tM4 x 8MM Socket Head Cap Screws have got me all hot and bothered. The 304 stainless steel is so shiny and beautiful, I almost feel bad using them to hold together my rickety old bookshelf. But beyond their physical beauty, these screws are truly exceptional. The socket head makes them easy to screw in and out, even with my wonky little screwdriver, and the cap ensures that they stay securely in place. And let's not forget the quantity - 100 screws! I don't know what I'm going to do with all of them, but I feel like I'm ready to take on any DIY project that comes my way. I'm not sure what kind of magical properties these screws have, but they seem to have brought out my inner handyman. I've been scouring my house for things to fix, and I've never felt more empowered. My cat looks a little worried, but I'm pretty sure he's just jealous of my new screws. In short, if you're in the market for some screws, look no further. These tM4 x 8MM Socket Head Cap Screws are the real deal. They're beautiful, easy to use, and come in a quantity that will make you feel like a DIY king or queen. Buy them. You won't regret it.

They are in a large quantity (~100) and are in good quality. I needed them to be stainless steel to avoid rust where I used them in a mixture of water and glycerol. The bolts are very good.

Fasteners are nice quality.
