براغي ماكينة #4-40 | رأس تثبيت بمحرك مشقوق | فولاذ مقاوم للصدأ 18/8 (800 / عبوة)

I needed a bulk pack of #4-40 screws for a panel project, and these stainless steel ones came with a slotted drive that fit my old screwdriver perfectly. The 800 count means I won’t run out anytime soon.

The binding head sits flush against the panel, and the slotted drive cuts cleanly with a standard screwdriver—no stripping even after a few installs. The 18/8 stainless steel feels solid and hasn't shown a hint of corrosion in my damp shop.

Finally, a binding head screw that actually sinks flush without splitting the wood. The slots are deep and clean, so my driver doesn't cam out on these #4-40s. These are going to hold up my outdoor sensor box for a long time.
