KROIL attacks rust and corrosion to help loosen frozen or seized metal fasteners such as nuts, bolts, screws, studs, hinges, tools, pulleys, chains or valves. Safe on all metals, it is ideal for stuck parts on cars, trucks, ATVs, fleet, farm and agriculture engines and equipment.

  • PRO GRADE: trusted by the professionals
  • SIMPLIFIES REPAIRS, MAGNIFIES MUSCLE: gives you all the leverage you need for those stubborn jobs
  • APPLICATIONS: Use on nuts, bolts, studs, screws, pulleys, shafts, valves, chains, tools, bearings, and any corroded threads or seized metal fasteners

I have been using Kroil for many years. I have MG Midget that I am restoring and updating. Kroil allows me to remove many rusted nuts and other screwed in devices such as drain plug fittings.
