Customer Reviews (4.8 / 5 · 5 reviews)

Harper ★★★★★

Used a dozen of these to repair a small jig at work, and the hex socket drive made seating them in tight spots easy. The full threading gripped well in thin aluminum, so I'll definitely grab another pack when needed.

Madison J. ★★★★★

The black oxide finish on these M2.5 screws is really uniform and seems tough—no flaking when I tightened them into my jig. The hex drive seats perfectly with a 1.5mm bit, and having 600 in the pack means I won't run out mid-project.

Sofia ★★★★★

I needed tiny screws for a precision instrument, and these fit perfectly. The black oxide coating seems durable, and all 600 pieces arrived neatly packed without any issues.
