براغي رأس سداسية 1-8 × 3-3/4 بوصة | صناعة أمريكية | درجة 8 فولاذ مطلي بالزنك الأصفر (35/عبوة)

The yellow zinc finish held up perfectly during assembly with no flaking, and every one of the 35 screws had clean, sharp threads that bit right into the tapped holes. I’m using them to secure a heavy steel jig on a shop press, and the Grade 8 hardness gives me real confidence at full torque.

These cap screws threaded in smoothly with a socket drive, and the yellow zinc coating looks exactly like the photos. The 1"-8 thread size matched my older machinery perfectly.

I needed some heavy-duty fasteners for a trailer hitch repair, and these Grade 8 cap screws fit perfectly with a standard socket. The yellow zinc coating feels tough and looks clean, and having a full 35-count pack means I’ve got spares for future projects.
