براغي رأس سداسي 9/16-12 × 2-1/2 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (25 / عبوة)

The yellow zinc finish on these bolts looks great and resists rust well in my damp shop. I used them to secure a heavy motor mount and the partially threaded shank made alignment easy. They drove in smoothly with a socket and the hex head held up to a good amount of torque.

Managed to torque these to spec without the threads stripping or the hex head rounding off, which I appreciate for a repair on my milling machine. The yellow zinc finish looks clean and seems pretty corrosion-resistant out of the package.

The partial threading on these 9/16-12 grade 5 screws made alignment a breeze when I was bolting a heavy motor mount, and the yellow zinc finish has held up nicely against shop grime. They drove in cleanly with a socket, no stripped heads or rough edges.
