براغي رأس سداسية 3/8-24 × 7/8 بوصة | فولاذ درجة 5 بزنك أصفر | ملولبة بالكامل (100/عبوة)

The threads are clean and started easily by hand, which saved me time on a machinery repair. These hex head screws hold tight with a socket, and the yellow zinc finish looks good against the steel frame.

Used a socket on these 3/8-24 cap screws and they seated perfectly into the machinery mount without any cross-threading. The yellow zinc coating on the grade 5 steel looks consistent across all hundred pieces, which saves time sorting.

I needed a hundred of these for a jig I’m building and they all threaded smoothly into tapped holes without any binding. The yellow zinc finish looks clean and has held up fine against a few accidental wrench scrapes.
