براغي رأس سداسي 1/2-13 × 6 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئيًا (100/عبوة)

Used these to secure a heavy-duty workbench frame and the hex heads gave my socket wrench plenty of grip without stripping. The zinc finish on the partially threaded shaft seems solid.

The threading is clean and consistent on every single bolt, which saved me time during assembly on a heavy-duty jig I’m building. These grade 8 screws feel solid, and the zinc coating looks uniform with no bare spots. Exactly what I needed for the job.

I needed some heavy-duty bolts for a trailer hitch project and these Grade 8 cap screws handled the torque without any issues. The partially threaded shank made alignment easier than I expected, and the zinc plating has a clean, uniform finish.
