براغي سداسية ثقيلة 3/4-10 × 5 بوصة | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئياً (45 / عبوة)

I needed these for a machine assembly job and the zinc plating on these hex cap screws held up well against my wrench without any galling. The partially threaded shaft gave just the right grip depth for my application.

The heavy hex head on these 3/4-10 screws gives my wrench a solid grip without slipping, and the zinc coating has held up well in my damp garage. Used a dozen so far on a press frame and they seated perfectly with no galling—exactly what I needed for a reliable bolted joint.

The threads cut clean and the zinc coating is even, no flaking when I torqued them down on a jig frame. Partially threaded length was just right for pulling two flanges together without bottoming out. Solid pack of 45 for the price, these won’t be the ones that fail.
