5/16" X 3-1/4" دبابيس زنبركية | مشقوقة | فولاذ مطلي بالزنك (500 / عبوة)

Exactly what I needed for a vibration-prone mower deck assembly. The zinc plating looks consistent and the slotted head made installation much easier than solid pins.

Pushed these into a heavy-duty gate hinge to replace some worn-out bolts, and the zinc plating is holding up well despite constant rain and vibration. They seated firmly with no wobble, exactly what I needed for a shear load application.

Just the right size for securing a trailer hitch pin, and the zinc plating looks solid so far—no rust after a few weeks in the weather. These handled the vibration on my mower deck without loosening up.
