Customer Reviews (4.8 / 5 · 5 reviews)

Joseph ★★★★★

The threads cut clean and true on my lathe, no binding or galling when I torqued them down. For a critical 4-1/2 inch application, these PFC9 bolts in yellow zinc are exactly what I needed.

William ★★★★★

The yellow zinc coating is holding up well on my press build, even in a damp shop. These 1-inch coarse threads drove cleanly into the plate without any binding.

Elizabeth R. ★★★★★

The yellow zinc coating is a nice touch on these — they've got a solid industrial look and the threads were clean right out of the package. Used them to bolt down a heavy base plate and they seated without any binding.
