براغي رأس سداسي ثقيل 7/8-9 × 10 بوصة | ASTM A193 B7 سبيكة فولاذ عادي | خيط جزئي (20/عبوة)

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.

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.

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.
