These locknuts are suitable for applications requiring an exceptional level of accuracy for specific applications where space is limited. PRT locknuts are 25-50% thinner than our PRN precision locknut series, and have a smaller outer diameter. They share the same envelope dimensions as NTH locknuts; but the PRT series has better surface finish, tighter dimensional tolerances, and more locking positions. These locknuts provide positive locking in applications with limited shaft space such as Aerospace, electronics, and machine tool.
