• Corrosion seizing the nut to the stud

🛠️ Service Notes

• This is the 5/16 size, so check the thread on the stud before ordering rather than judging by the look of the nut
• Renew rather than reuse where the nut has been heated or cut off, and replace any stud with damaged threads at the same time
