In short, this set sucks! Yes, there are two properly sized 16mm screws, but none of us paid $20 for a pair of screws. The problem is that the washers that this application requires don't turn on the bolt to allow you to adjust the caster. These washers are stamped from cheap mild steel. I promise you that if you try to spin a reel, the washers will spin around the bolts and you won't be able to maintain the reel's adjustment. A lot of people install them and then take the truck to the shop. So
