Customer Reviews (4.6 / 5 · 5 reviews)

Sebastian ★★★★★

The box arrived with all 50 screws perfectly threaded on the bottom half, and the yellow zinc coating looks even better in person than in the photos. I used them to bolt down a steel workbench frame and the heads seated cleanly with a socket, no stripping at all.

Ella ★★★★★

Used these to rebuild a press attachment at work, and the partial threading made alignment so much easier. The yellow zinc has held up well without any corrosion after a few weeks in a humid shop.

Natalie Y. ★★★★★

Finally got around to installing these on my press jig and the yellow zinc finish is holding up nicely against the grease and grime. The partially threaded shank really helps keep the alignment true when fastening thick brackets.
