براغي ماكينة #4-40 × 9/16 بوصة | رأس بانة فيليبس | فولاذ مطلي بالزنك ثلاثي التكافؤ (5000 / عبوة)

I've been searching for a bulk box of these #4-40s for ages, and the trivalent zinc finish looks clean and uniform straight out of the bag. The phillips heads drive without stripping, and 5000 pieces means I won't be reordering for a long time.

Finally found someone offering a 5000-pack of #4-40 x 9/16" screws; the trivalent zinc finish looks consistent across all of them. Using these for mounting steel panels and the Phillips drive seats perfectly without cam-out.

Ordered a full box for a panel assembly job and every single screw came out clean, no bent threads or mangled heads. The trivalent zinc finish is uniform and makes them slide into tapped holes without any binding. For the price per piece, this is a no-brainer restock item for my bench.
