#4-40 × 5/16" براغي ماكينة | رأس دائري محزز | نحاس (800/عبوة)

The bag of 800 is a solid deal if you're restoring old switch plates or radios—these brass #4-40s match the originals perfectly and the slotted heads take a standard screwdriver without cam-out. They're non-magnetic too, which mattered to me for a small brass compass project.

I needed slotted brass screws for a vintage lamp restoration, and these #4-40s fit perfectly with a clean, flush finish. The slot cut is deep enough that my old driver didn't cam out once.

The bag of 800 means I won't run out mid-project, and the slot heads bite nicely with a standard driver. These are my go-to for any small brass trim where corrosion resistance matters.
