Aurora ★★★★★

Needed a batch of flat head screws for my 3D printer's aluminum frame, and these M3 x 12mm alloy steel ones fit perfectly with no wobble. The hex socket drive made installation a breeze with my allen key, and the heads sit flush like they're supposed to.

Benjamin ★★★★★

The hex drive grabbed perfectly on every single one of these M3 screws—no stripped heads, even in tight spots. Alloy steel feels solid for the price, and the flat heads sit flush on my jig plate. Really clean bulk pack for precision builds.

Michael ★★★★★

Went through about 200 of these for a jig assembly and not a single stripped socket or bad thread. The alloy steel holds up way better than the stainless ones I've used before, and the hex drive bites clean every time. For four hundred pieces at this price, it's hard to beat.
