براغي رأس سداسي 1/4-20 X 1-5/8" | فولاذ درجة 5 زنك أصفر | ملولب جزئيًا (200 / عبوة)

These have a nice tight thread fit that makes assembly feel solid. The yellow zinc coating looks clean and uniform, and they drove in smoothly with a socket wrench. Perfect for attaching brackets to a steel frame.

I used these to rebuild a small trailer hitch assembly and the partial threading grabbed perfectly in the receiver nut. The hex heads held up under a torque wrench without stripping, which was exactly what I needed for a secure fit.

These bolts held up perfectly when I torqued them down on my trailer hitch, the yellow zinc finish gives good corrosion protection. The partial threading made assembly much quicker since I didn't have to chase threads through the mounting plate.
