براغي ماكينة مقاس #4-40 × 1/4 بوصة | رأس بان سلوثد درايف | فولاذ مطلي بالزنك (5000 / عبوة)

I needed a bulk supply of #4-40 screws for a panel project, and these pan head slotted ones worked perfectly with standard screwdrivers. The zinc plating gives them a clean, uniform look, and at 5000 per pack, I won’t be running out anytime soon.

The zinc plating is holding up nicely so far, no rust spots after a few weeks in a damp basement. I’ve used maybe two hundred of these #4-40s on metal brackets and they’ve all seated cleanly without stripping, which is more than I can say for cheaper packs.

Picked up a 5,000-pack for a project rebuilding old radio chassis, and the pan head profile seats nicely in counterbores without binding. The slotted drive works perfectly with a standard screwdriver, and the zinc coating seems uniform across all of them—no stripped heads so far.
