Pack Of 50 M5-0.8 X 16Mm Button Socket Cap Screws | ISO 7380 Standard | Class 10.9 Grade Alloy Steel | Black Oxide Finish | Hex Drive Review

These fasteners are well made with 0 rejects. The heads do not easily strip out like other brands. The black coating will last through an install and removal 2x before it begins to fade to the underlying copper colored coating.

Ordered these after being recommended that these are the sizes for radions. Fits perfectly on my radion xr30. There were only 30 screws in the box, not 50..

I use these to replace thumb screws on GoPro mounts that I use for lights. I like they give a streamlined, cleaner look, The lights are adjusted only once so I don't need handles sticking out! They're black so they blend with the black mounts. I have also (not mastered) painted these to a red anodized look. However you can tighten but can't torque these down. The hex will slip before you can torque it to 5nm, but are tight enough they will not loosen after a few months & are still tight.

They work and they were cheap so they are fine, but despite the black coating and showing up absolutely drenched in oil, they started rusting IMMEDIATELY. I was using them on a panel that people are going to be touching and leaning on so they are going to rust a lot more as it gets used. That’s disappointing. I don’t think they even lasted 3 days before being covered in visible rust.

I got 43 screws. Not the advertised 50. Apparently that is close enough right? Good thing I didn’t actually need 50. Minutes

Was lacking about 30 screws. I realized when I ran out counting them on the project. Its no where near 100 screws here short about 30.
