براغي رأس سداسي 1/2-13 × 2-3/4" | صناعة أمريكية | سبيكة PFC9 صفراء زنك (50/عبوة)

Grabbed a pack for replacing some worn bolts on a press, and the yellow zinc coating looks like it’ll hold up better than the old ones. Threads were clean and the hex head grabbed my wrench perfectly on the first try.

These are going straight into a jig I’m building; the hex heads let me get a solid grip with a socket wrench without stripping. The threads cut cleanly in pre-tapped holes, and the yellow zinc finish looks like it’ll hold up well in my shop.

The yellow zinc coating on these screws is even and consistent, so they should hold up well in my shop environment. They threaded cleanly into my existing tapped holes without any binding or cross-threading.
