Hey Nathan, the trailer hub part # TRU55FR that you referenced uses 1/2-20 wheel studs. The rest of the specs are:

Thread size: 1/2"-20 UNF
Overall length: 2.06"
Knurl diameter: 0.630"
Grade: 8
Finish: Zinc plated

The closest option we have is the part # LC52ZP which is a set of 6 that is correct size. Did you break some studs by chance?
