براغي رأس سداسي مقاس 9/16-18 × 4-1/2" | فولاذ درجة 5 زنك أصفر | خيوط جزئية (25 / عبوة)

These bolts threaded perfectly into the frame I’m building, and the yellow zinc finish looks good and seems durable. The partial threading really helped get a tight joint on the thicker bracket.

Needed these for a small machinery repair and the partially threaded design made alignment way easier than I expected. Yellow zinc coating looks clean and the hex head grabbed a socket without any stripping. Pack of 25 feels like a solid value for the price.

I’ve been using these 9/16‑18 cap screws for a heavy equipment repair and the grade 5 steel with yellow zinc is holding up great. The partial threading made it easy to get a solid bite without binding too early. Exactly what I needed for a secure, lasting fit.
