براغي رأس سداسية 5/8-11 × 5-1/2 بوصة | صناعة أمريكية | فولاذ سبائكي PFC9 مطلي بالزنك الأصفر (25/عبوة)

The hex head on these cap screws made torquing them down with a socket a breeze, and the yellow zinc coating looks tough enough to resist rust. I'm using them on a heavy press rebuild, and the USA-made quality is evident in the precise threads. No complaints here.

These bolts are exactly what I needed for reattaching a heavy drive shaft on my milling machine. The threads were clean and started smoothly, and the PFC9 alloy steel feels seriously tough even before I torqued them down. Six of them held everything solid with no complaints.

The yellow zinc coating looks great and the threads were clean and sharp—no burs to fight with. These went into my press frame without any binding, and the hex heads gave my socket a solid grip.
