Customer Reviews (4.6 / 5 · 5 reviews)

Hannah W. ★★★★★

I needed these for a heavy equipment repair and the partially threaded section made alignment much easier than I expected. The threads engaged smoothly and they torqued down without any issues.

Jacob T. ★★★★★

I was a little worried the threads might be too tight for my application, but they ran smoothly into the pre-tapped holes without binding. The 10-inch length on these hex cap screws gave me plenty of grip for mounting some heavy brackets. Definitely feel solid enough for machinery work.

Joshua ★★★★★

The threading is clean and started easily with a wrench, and the 10-inch length gave me plenty of grip for a heavy steel beam tie-down. No stripping or galling on the first few uses, which is exactly what I needed for this job.
