Video tutorial on how to remove a seized fastener while preventing the head from being stripped with minimal tools. This is an especially great method for removing screwdriver or socket head fasteners. No power tools are required, here I am using a hand impact driver. I originally purchased the tool back when I was working on Japanese motorcycles as they are known to have softer fasteners, as a phillips screw head this can be easily stripped. I used this in one of my videos for removing seized exhaust bolts on a small engine too.

Tools/Supplies Needed:

  • pick or scriber
  • hand impact driver
  • sockets or driver bits
  • hammer

Step 1:

The impact driver can work clockwise or counter clockwise, it’s able to provide a shock to the fastener while giving a twisting action. Here I’ll be using this brake rotor retaining fastener as an example. I believe the car has a slightly larger diameter for fasteners, but on some vehicles beyond stripping these bolts can also break easily too.

Step 2:

First ensure the head of the fastener is clean, use a pick or scriber to remove any rust or dirt if needed. This will help for maximum contact so the driver bit is seated correctly.

Using a hammer, here I am just using a small ball pean, but a larger one can be use for those tighter fasteners. Apply a twisting pressure as if you were removing the fastener by hand, this will also set the direction of the tool.

Then continue to hit the rear of the tool with a hammer. The force will help push the tool inward, allowing the driver to apply full pressure in the head of the fastener to prevent stripping and also give shock to the break free rust or corrosion. Kind of similar to how an impact gun can break away rust, but without the need of running an air hose, extension cord, or purchasing costly tools which you may not have.

Step 3:

And now after a few hits the fastener is loose.

If you missed it, I’ll slow down the footage for a better look. As you can see during the hit, the fastener does make a slight rotation.
