براغي رأس سداسي 3/4-10 × 3-1/4" | صناعة أمريكية | فولاذ سبائكي درجة L9 مطلي بالزنك الأصفر | ملولبة جزئيًا (20 / عبوة)

The partially threaded design made aligning the mounting bracket way easier than dealing with fully threaded rods on my press rebuild. Grade L9 hex heads seated cleanly with a socket, and all twenty cut threads without any galling.

The yellow zinc coating on these bolts looks great and resists rust well, and the partially threaded shaft gave me plenty of grip for my equipment mount. Used a 1-1/8" socket and they seated perfectly in pre-drilled holes with no stripping.

Put these on a heavy press fitting yesterday—the partial threading made aligning the nut a breeze without binding. The hex head seated perfectly with a standard socket, and the yellow zinc coating seems like it'll hold up well in our shop environment.
