براغي رأس سداسي 9/16-18 × 2-1/2" | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (25 / عبوة)

The yellow zinc coating on these bolts is smooth and uniform, and the partial threading made them perfect for aligning a jig on my press. They seated cleanly with a 9/16 socket and held firm under torque.

Needed to swap out some worn bolts on an old conveyor, and these hex heads fit perfectly with a socket. The yellow zinc coating looks solid, and the partial threading made alignment easier than I expected.

Installed a dozen of these on a press frame yesterday, the hex head gave my socket a solid bite without any stripping. Yellow zinc finish looks clean and the partial threading made alignment quick.
