براغي رأس سداسي 1 بوصة-14 × 5-1/2 بوصة | صناعة أمريكية | سبائك فولاذ درجة L9 مطلي بالزنك الأصفر | خيط جزئي (10/عبوة)

I needed some heavy-duty bolts for a repair on an industrial press, and these L9 alloy steel screws handled the torque without any sign of stripping. The yellow zinc coating looks like it will hold up well in a shop environment too.

The partially threaded design made aligning the plate much easier, and the yellow zinc coating looks clean on the frame. These L9 bolts torqued down smooth without any galling, and the 5-1/2" length was exactly what the bracket called for. Solid set for the price.

The hex head on these cap screws gripped perfectly with my socket, and the yellow zinc coating looks great for resisting rust in my shop. The partial threading made alignment much easier when I was assembling a heavy machine base.
