Customer Reviews (4.6 / 5 · 5 reviews)

Violet ★★★★★

Used these to bolt down a jig plate for a milling setup, and the hex socket drive seated perfectly with no stripping. The 12.9 alloy steel feels rock solid, and the black oxide coating hasn’t shown a single speck of rust after a month of coolant exposure. That’s a win in my book.

Madison S. ★★★★★

The black oxide finish on these screws gives them a nice, uniform look that resists smudges during assembly. I used them to secure a heavy-duty fixture and the Class 12.9 strength handled the torque without any flex. For the price per piece, you get a solid, consistent batch that threads cleanly eve

Avery ★★★★★

Used a few of these to fix a jig that kept loosening under vibration, and the 12.9 alloy steel with black oxide finish has held up perfectly for a month of heavy use. The hex socket drive seats cleanly and the threading is uniform all the way down.
