Edward U. ★★★★★

Had to cut them down for a custom bracket on my press — the Class 8.8 steel held up without any strip or play on the threads. The partial threading made alignment way easier than a fully threaded bolt would have.

Mia U. ★★★★★

Used these on a trailer hitch repair I was doing, and the partial threading made alignment much easier than a fully threaded bolt would have. The zinc coating seems decent, no rust after a week of rain. Solid feel when torquing them down.

Lily I. ★★★★★

I needed longer M12 bolts for a machine frame I’m assembling, and the 300mm length with partial threading let me get good bite into the threaded hole. The zinc coating seems evenly applied, no flaking or rough spots.
