مسامير آلية سداسية 5/16-18 × 1-1/2 بوصة | فولاذ مقاوم للصدأ 18/8 | ملولبة جزئيًا (50 / عبوة)

These bolts fit perfectly in my trailer hitch mount, and the stainless steel is a huge upgrade from the plated ones I had before. The unthreaded grip section made alignment much easier during assembly.

These bolts are perfect for my trailer hitch build — the 18/8 stainless really resists corrosion. The partially threaded shank made alignment a breeze compared to fully threaded ones, and the hex head grabbed nicely with a socket.

Used a handful to secure a metal bracket to a wooden post; the partially threaded shank gave a nice tight fit without wobble. They're stainless, so no worries about rust in the weather. Only minor thing is the package came with one bolt that had a slightly off-thread.
