Customer Reviews (4.8 / 5 · 5 reviews)

Aurora ★★★★★

Yellow zinc coating looks even better in person than in the catalog, and the threads are clean all the way down. Took these straight to the shop floor for a jig setup and every one seated without a hitch.

David J. ★★★★★

The hex heads on these bolts gripped my socket wrench perfectly without slipping. Exactly the right thread engagement for mounting a heavy motor bracket. Nice to have a full hundred pieces for the price.

Harper ★★★★★

I needed some heavy-duty bolts for a shop press rebuild, and these L9 screws handled the torque without stripping. The yellow zinc finish is consistent across all 100 pieces, and the threads are clean from end to end.
