Customer Reviews (4.2 / 5 · 5 reviews)

Grace ★★★★★

The partial threads really bite into the frame without slipping, and the yellow zinc coating looks clean and professional on my press setup. These Grade L9 bolts torqued down perfectly with a socket, no stripping or deformation at all.

Alexander ★★★★★

I've been using these for heavy equipment assembly and the yellow zinc coating seems to hold up better than other fasteners I've tried. The partial threading made alignment easier during installation.

Joshua G. ★★★★☆

The yellow zinc coating looks better in person than on screen, and the threading is clean all the way down. Used them to bolt up a jig frame and they seated without any binding. Only wish the box had a divider so the loose ones didn't clank around.
