براغي رأس سداسي 3/4-10 × 4-1/2 بوصة | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (55/عبوة)

The partially threaded design made these perfect for bolting a heavy guard plate without bottoming out, and the hex head gripped firmly with a socket wrench. Pack of 55 should last me through several equipment repairs.

Went through the whole box seating a pump base and not one fought me on the threads. The yellow zinc finish still looks clean after a few days of rain and grime, and the partial threads gave the grip I needed without bottoming out.

These bolts threaded perfectly into my existing tapped holes without any binding, and the yellow zinc coating looks really clean. The partial threading made aligning the heavy bracket much easier than dealing with a fully threaded rod.
