Michael ★★★★★

I needed some tiny but strong screws for a jig I’m building, and these M2 x 3mm cap screws fit perfectly with that Class 12.9 hardness. The hex socket drive made installation a breeze, and the zinc plating looks clean.

Stella ★★★★★

For a 600-pack of precision fasteners, the Class 12.9 alloy steel is the real deal—these hold torque way better than the random hardware-store bin screws I used to struggle with. The zinc plating gives them a clean, consistent finish, and the hex socket drive seats perfectly with my driver. Already

Ryan ★★★★★

These little M2s are perfect for my jig builds. The 12.9 alloy steel gives them a solid, sturdy feel, and the zinc plating has held up fine so far. 600 in a pack is a good deal for the price.
