Isabella ★★★★★

I grabbed these for a jig I was building, and the hex socket drive made installation a breeze without any stripping issues. The zinc finish also feels like it’ll resist rust better than the plain steel ones I had before.

Timothy ★★★★★

For a small hardware project these M4 hex socket screws were spot on. The trivalent zinc finish looks clean and consistent across all 400 fasteners. They seated perfectly flush in my jig’s countersunk holes.

Benjamin U. ★★★★★

I was pleasantly surprised by the quality of the zinc finish on these screws — it's even and much smoother than what I usually get from bulk hardware. They drove cleanly into my aluminum brackets without stripping the hex socket.
