Customer Reviews (4.8 / 5 · 5 reviews)

Robert S. ★★★★★

Needed to replace some beat-up bolts on an old press, and these grade L9s handled the torque without a hint of flex. The yellow zinc finish is a nice touch—keeps the rust away in our humid shop.

Henry G. ★★★★★

The yellow zinc coating held up fine tightening these down for a machine base, no flaking or galling even with a cheater bar on the hex head. For a 12-inch bolt at this grade, they came straight and true out of the package, threads cut clean. These are the kind you buy once and don't think about aga

Steven ★★★★★

Swapping out the old bolts on my press with these L9s and the difference is night and day. The partial thread made alignment a breeze, and the yellow zinc coating looks like it'll hold up well in the shop.
