Customer Reviews (4.8 / 5 · 5 reviews)

Michael Z. ★★★★★

The hex head grabbed my socket perfectly, and the yellow zinc coating on these Grade 8 screws looks tough enough for heavy machinery. I used them to secure a steel bracket on my trailer, and they drove in without any stripping.

Robert I. ★★★★★

I needed heavy-duty fasteners for a farm implement rebuild, and these hex heads drove in smoothly without any stripping. The threads are sharp and clean, and the Grade 8 steel gives me confidence they'll hold up under serious torque. Only wish the package had a few more for the price.

Jason ★★★★★

The yellow zinc finish on these Grade 8 bolts is holding up well under heavy loads, and they seated cleanly in my equipment mount without any cross-threading issues.
