براغي رأس سداسي 1/2-20 × 7/8" | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر | كامل الخيوط (50/عبوة)

These fit perfectly on my milling machine's T-nuts, and the yellow zinc coating looks like it'll hold up well. The threads are clean and catch smoothly right out of the package.

I was impressed by the solid feel of these Grade 8 steel cap screws when I torqued them down for a heavy equipment mount—the yellow zinc coating seems really durable. No stripping or galling on the threads, which I've had issues with on cheaper fasteners. These will be my go-to for any future indust

These bolts threaded perfectly into my milling table without any binding. The yellow zinc coating looks consistent and well applied across all fifty pieces.
