براغي رأس سداسي 1/4-20 × 1" | صناعة أمريكية | فولاذ سبيكة PFC9 أصفر زنك (200 / عبوة)

The yellow zinc finish on these is flawless and uniform across all 200 pieces, which matters when you're doing visible assembly work. Grabbed a wrench and drove a few into my equipment stand, and the PFC9 alloy steel threads cut clean without any binding.

Broke down and replaced some old bolts on my milling machine—these seated perfectly in the T-slots with no wobble. The yellow zinc is holding up well in my shop's humid air, too.

These threads cut clean and drive with zero cam-out, the PFC9 steel feels solid even under a stubborn nut. Packaging was neat too, all 200 accounted for and the yellow zinc finish looks proper on my equipment build.
