مسامير آلة سداسية 1/2-13 X 5" | فولاذ مجلفن بالغمس الساخن | ملولبة جزئيًا (50 / عبوة)

These bolts fit perfectly into my trailer's frame brackets, and the hot-dip galvanized coating already seems much more weather-resistant than standard zinc. The partially threaded shank gave me just the right amount of grip length without any extra threading.

I needed a strong, unthreaded section in the middle for a tight bolted connection, and these partially threaded 5-inch bolts provided exactly that grip length. They’re well-made and the hot-dip galvanizing looks like it will hold up to outdoor weather.

The galvanized coating on these bolts is thick and even, so they should hold up against moisture in my outdoor shed build. The unthreaded grip section let me cinch the frame tight without the threads chewing into the wood. Solid pack for the price.
