مسامير ربط سداسية 3/8-16 × 1-1/4" | فولاذ مطلي بالزنك الأصفر | ملولبة جزئيًا (1000 / عبوة)

Had to swap out rusted bolts on a trailer hitch, and these zinc plated ones slid right into the pre-drilled holes without binding. The partial threading gave just the right grip length for a snug connection.

Pulled a full pallet of these for a repair job last week and the partial threading made alignment way easier than fully threaded ones. The zinc yellow plating held up fine against the rain we got mid-project, no rust spots yet. Glad I bought the 1000 pack because I'll definitely use the rest.

The partially threaded shank made alignment a breeze during assembly, and the grip length really helps keep everything tight. I’ve used about half the box on a steel frame project so far with no stripped threads.
