براغي رأس سداسي #1/2-13 × 11 بوصة | درجة 5 فولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (120 / عبوة)

Installed these on a steel beam splice, and the 11" length was exactly what I needed to punch through a built-up section. The yellow zinc coating held up fine against a few rain showers during the install.

Had to swap out some older bolts on a press, and these 1/2-13 x 11" threaded right in without any binding. The yellow zinc finish looks uniform and the hex heads grabbed cleanly with a socket, though the partial threading means you need the right length for your setup.

Used these for mounting a heavy motor mount, and the yellow zinc coating kept rust off during a humid week. The hex heads grabbed cleanly with a socket, and the partial threading made alignment dead simple.
