براغي رأس سداسية 1/2-20 X 2-1/2" | فولاذ درجة 5 مطلي بالزنك الأصفر | سنون جزئية (50 / عبوة)

Got these for a heavy-duty press table rebuild and the partially threaded shank made alignment way easier than fully threaded bolts. The yellow zinc coating looks nice and seems like it'll hold up to shop grime.

Threaded a bunch of these into a jig frame this morning and the yellow zinc finish made them slide in smooth without any binding. Threads are clean and the partial thread gives solid grip for pulling two plates tight. Exactly what I needed for the rebuild.

Used these to replace some worn bolts on a piece of equipment, and the Grade 5 steel feels solid. My only small gripe is the partial threading could be a bit longer, but they held up fine under torque.
