براغي كاب سداسية ثقيلة 1-1/8-7 × 5" | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئيًا (20 / عبوة)

Used these A307 bolts to secure a heavy motor mount, and the zinc plating looks like it will resist rust well in my damp shop. The hex head gave my socket a solid grip, and all twenty threads ran true without binding.

Used these to secure a heavy steel bracket to a concrete base, and the zinc plating held up well against a bit of moisture during installation. The partial threading gave just the right grip depth for the 5-inch length — no stripping issues at all.

The threads cut smoothly and the partial threading makes alignment much easier in tight spots. These feel heavier and more substantial than the hardware store stuff I usually grab.
