How to Fix Stripped Lug Nut Stud Threads

Filing a stripped and damaged wheel stud

You may have been trying to loosen the rotor and nicked a lug nut stud with a hammer. This can cause minor damage to the threads. If the wheel stud isn’t bent, you may be able to repair the studs with a file.

File the stripped areas until they are removed and you can see the threads again.

Then thread a lug nut on and test how well the threads work.

If the lug nut can’t twist on past the damaged wheel stud threads, remove the lug nut and continue to file until the threads are visible and can work.

Wheel Stud Replacement Steps

  1. Remove the Brake Rotor

    You’ll have to remove the rotor to replace a bent or loosened lug nut stud—especially if it has broke off.

  2. Remove the Damaged Wheel Stud and Inspect the Splines

    Look at the lug nut stud and see if it’s reusable. Check the threads for unfixable damage.

  3. See If the Wheel Stud Is Bent

    Check the stud for straightness. You can’t reuse a bent wheel stud. You can roll it and see if it rolls smoothly instead of a bent one that may not roll far.

  4. Clean the Wheel Nut Lug Stud

    Use a wire wheel to clean up the stud, and then double-check how well the lug nut twists on.

  5. Clean the Front and Back of the Wheel Hub

    Remove any debris from the front and the back of the wheel hub with a die grinder and wire brush.

  6. Install the Wheel Lug Nut Stud with Red Thread Locker, a Spacer, and a Socket and Impact Wrench

    Place red thread locker at the top of the lug nut stud splines that will sit in the wheel hub. Tighten the stud with a spacer and socket. Use a spacer with a washer or apply grease to the hub so the spacer can secure. Tighten the wheel stud until the back of it lays against the hub, and install it as straight as possible.
