براغي ذات رأس سداسي 7/8-9 × 3-3/4 بوصة | صناعة أمريكية | فولاذ سبائكي درجة L9 مطلي بالزنك الأصفر | ملولبة جزئياً (65 / عبوة)

The hex heads fit my socket perfectly, and the yellow zinc finish looks clean even in a greasy shop environment. Threaded right into the steel framework without any binding at all.

Used them to bolt down a heavy conveyor bracket and the L9 yellow zinc held up great under the torque— no stripping, no rust worries. Threads were clean and the partial threading made seating the nut a breeze.

The partially threaded design made alignment much easier when fastening this to a thick steel bracket. These Grade L9 bolts torqued down smoothly without any galling, and the yellow zinc coating looks like it will hold up well in a shop environment.
