براغي رأس سداسي 3/4-10 × 5 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئياً (55 / عبوة)

Used these to secure a heavy-duty press base to the concrete floor — the partial threading made alignment much easier than going fully threaded. The zinc coating looks clean and should hold up fine in a dry shop environment.

These came in a tidy package of 55, and the zinc plating on the grade 8 steel looks even and durable. The partial threading is perfect for clamping down thick brackets without bottoming out. Used about a dozen so far on a heavy jig and they've held torque without a hint of stripping.

Finally got around to using these for a heavy machinery mount and the zinc plating held up perfectly against some rough handling. The partial threading made alignment a lot easier than dealing with a fully threaded bolt in a tight spot. Exactly what I needed for the job.
