Chloe W. ★★★★★

I needed a solid batch of M4 screws for a jig I’m building, and these Class 8.8 steel ones feel plenty tough for the torque. The zinc coating looks consistent, no flaking or rough edges I can see. They drove in cleanly with a hex key and held tight.

Sofia I. ★★★★★

These M4 bolts threaded smoothly into existing nuts without any binding, and the zinc coating gives them a clean, uniform look. For the price of a 600-pack, I'm set for several projects—the Class 8.8 steel feels sturdy enough for my machine assembly work.

Evelyn J. ★★★★★

The hex heads seat cleanly with a 7mm socket, and the fully threaded shafts grip firmly all the way through my brackets. I've used about half the box on a weekend project and not a single one stripped or snapped.
