براغي آلة #4-40 × 3/4 بوصة | رأس مقبس فيليبس | فولاذ أكسيد أسود (2000/عبوة)

The black oxide finish on these screws gives them a nice, uniform look that matches perfectly with the dark interior of the enclosure I'm building. They thread smoothly into pre-tapped holes without any binding, and having two thousand in a single package means I won't run out mid-project.

Finally, a #4-40 screw that actually fits perfectly into my enclosure panels without stripping – the black oxide finish blends right in. The pan head and Phillips drive made installation a breeze, and I still have plenty left for future projects.

I needed a decent quantity for a few small enclosure projects, and these #4-40 screws worked well for mounting circuit boards. The Phillips heads drive consistently without stripping, though I wish the 3/4" length was available in a slightly smaller pack.
