Customer Reviews (4.6 / 5 · 5 reviews)

Thomas N. ★★★★★

Was pleasantly surprised by the precise threading on these—they started by hand without any binding. The yellow zinc finish on the Grade L9 steel looks clean and seems durable for heavy use.

Henry U. ★★★★★

The partial threading made installation on our equipment frame much easier since the unthreaded shank aligns perfectly in the hole before the threads engage. These bolts feel solid in the hand, and the yellow zinc coating has a nice, consistent finish.

Aurora L. ★★★★★

These hex heads grab cleanly with a socket—no stripping or slipping like cheaper bolts. The yellow zinc coating looks evenly applied, and having eight in the pack is just right for a weekend project.
