Proflow Aluminium Chassis Jam Nut L-H 5/8-18' 3/4' Hex

If you have spherical rod ends on your vehicle, you'll probably need jam nuts, right? You might also need them for tie-rod ends or other types of fittings and connectors. Proflow jam nuts are made from either steel (coated for corrosion prevention) or aluminum and they're available with either right hand or left hand threads.
