Hazel ★★★★★

These little #3-48s are exactly what my precision assembly needed—the hex socket drive takes the guesswork out of seating them flush, and the black oxide finish feels solid right out of the bag. I've burned through cheaper packs before, but these held up without a single stripped head across all 100

James U. ★★★★★

Needed some tiny screws for a jig I’m building, and these black oxide ones are both strong and easy to grip with a hex key. The threads cut cleanly into the metal without binding.

Victoria ★★★★★

The hex drive on these #3-48 screws engages perfectly, no wobble or stripping. Worked great for securing a small jig fixture on my mill.
