دبابيس كوتر 5/16" × 1-3/4" | فولاذ مطلي بالزنك (100 / عبوة)

The zinc plating on these 5/16" pins looks even and solid, so they shouldn't rust out in a season. I used a handful to secure a tractor hitch, and the 1-3/4" length held perfectly with no bending.

Finally found some heavy-duty cotter pins that don't bend when I'm tightening them down. The 5/16" diameter fits perfectly through my tractor hitch pins, and the zinc coating hasn't shown any rust after a few weeks outside.

Was relieved to see these fit perfectly on my trailer hitch pins—the 5/16" diameter was exactly what I needed. The zinc plating looks clean and should resist rust well.
