Customer Reviews (4.4 / 5 · 5 reviews)

Eva Y. ★★★★★

Torqued them down to spec on a heavy press frame and the hex head held without rounding. The partial threading made alignment easier than I expected for this size bolt.

Edward ★★★★★

Threads cut clean and seated perfectly into the coupling flange on my press—no wobble at all. The 10.9 steel feels reassuringly solid for a job this size, and the partial threading gave me just the grip I needed.

Harper ★★★★★

The 4-pack is exactly what I needed for a heavy equipment repair. The 80mm length and partial threading let me get a solid bite without bottoming out in the blind hole.
