#4-40 × 5/8" براغي ماكينة | رأس مقبس مع شق | فولاذ عادي (3,000 / عبوة)

I needed a bulk supply for small-scale assembly work, and the slot on these #4-40 pan heads is cleanly cut—no burrs to fight with. They thread smoothly into tapped holes without binding, which saves time on the line.

Was worried about the drive slitting, but the pan head held up fine while I was securing a light fixture bracket. Pack of 3,000 means I'll have these #4-40s for years.

For a simple indoor project, these plain steel screws did the job without any fuss. The #4-40 threading matched my existing nuts perfectly, and the 5/8" length was ideal for the bracket I was repairing. A whole box of 3,000 means I won't need to restock for a long time.
