James ★★★★★

After stripping the head on a standard Phillips trying to get these to bite in tight spaces, the 6-lobe drive on these M4s really saved the day. The zinc and bake finish feels tough and hasn't shown any rust yet after a few weeks outdoors.

Daniel A. ★★★★★

Needed a strong, reliable fastener for a tight mounting bracket—these M4 x 20mm six-lobe screws seated perfectly with a hex driver and the head sits flush as expected. The zinc coating looks even and hasn't shown any rust after a few weeks on a damp workbench.

Lily ★★★★★

Had a few stripped screws on a project, so I grabbed these for the hard spots. The heat-treated steel feels noticeably tougher than standard hardware I've used before, and the 90-degree flat head sits perfectly flush in my aluminum frame.
