Mia W. ★★★★★

Got these for a small decorative box I was restoring and they thread in cleanly without stripping. The brass finish blends right in with the antique hardware, and having 600 in the pack means I've got plenty left for future projects.

Christopher ★★★★★

The brass finish on these #4-40 screws is a perfect match for my antique clock restoration project. Each one threads cleanly into the old tapped holes without binding, and the slotted drive holds the screwdriver nicely. A full 600-count package means I’ve got plenty left for future repairs.

Hannah B. ★★★★★

I was worried about finding the right slotted head screws for a small brass lamp repair, but these #4-40s fit perfectly and the 600 count is way more than I'll ever need. The threads cut cleanly into the brass without any binding.
