1/4-20 x 1/2" Button Head Socket Cap Screws, Allen Socket Drive, Black Oxide, Grade 10.9 Alloy Steel, Fully Threaded, 50 PCS

I got these for a desk I was making to match with the threaded inserts I was putting in. These have a nice finish and good fit with the inserts. I would definitely buy again.

Good quality. Doesnt strip out.

Good value. Good seller. I didn't pay attention to the dissimilar metals I was attaching, so now I'm fighting rust. I never finished chemistry class because I kept finding ways to light things on fire. Yeah, shop class had the same issue. Home economics... Recess...

These are good screws, but they do strip out if you are not careful. I got these to put together a desk. I installed the desk, took it apart, and put it together again (over the course of a move). Some of the screws started to strip. That said, they hold well once assembled. The threads are generally okay as well.

Nice product

Lost a screw and washer on my corsa intake and these fit perfectly

I purchased these to use with a set of t-nuts on the roof rack of my vehicle. Within a week of installation all the heads are rusting!!! Whatever coating is on them does not protect them. I'm stuck with having to replace all of the bolts now.

First order arrived spilled with missing screws - apparently Amazon's fault.Replacement was correct count.
