Adam O. ★★★★★

Tiny as they are, these #1-72 screws went into my precision jig without any cross-threading, and the hex socket drive grabbed the allen key cleanly every time. The thermal black oxide coating hasn’t chipped despite me tightening and loosening them a few times already. For a hundred pack at this size

Joshua ★★★★★

The black oxide finish looks sharp and uniform across all 100 pieces, which is exactly what I need for a clean jig build. They seated perfectly in the hex drive without any stripped heads, so no wasted fasteners.

Timothy ★★★★★

I needed a small batch of these for a lathe tailstock repair, and the hex drive seated perfectly without any stripping. The alloy steel feels dense and strong in hand, and the black oxide finish has held up well against light oil exposure so far.
