Customer Reviews (4.8 / 5 · 5 reviews)

Mia Y. ★★★★★

The yellow zinc coating on these Grade L9 bolts is flawless, and they threaded smoothly into my press jig without any binding. Exactly what I needed for a high-stress assembly that regular hardware wouldn't handle.

Lily ★★★★★

I needed some heavy-duty bolts for a shop press rebuild, and these L9 alloy steel cap screws handled the torque without any sign of stripping. The yellow zinc coating is a nice bonus for resisting rust in the garage.

Steven O. ★★★★★

The threads cut clean and the hex heads fit my sockets perfectly without slipping. These bolts held up under serious torque on my press rebuild with no issues.
