tools for the job:

  • Hammer

  • Hook tool for hooking and pulling the sleeve out, this can be fashioned from a “T” handled hex key.

  • Needle nose pliers

  • A magnet of some kind that will fit into the bolt hole

  • Adjustable wrench, 1/2” wrench, 9/16” wrench, and 3/4” wrench (if using Hurley jr tool)

  • Tap tool of the corresponding size to sleeve being pulled (3/8”-16 for 3/8” 5pc bolt)

  • Appropriately sized threaded rod adaptor for extraction tool (3/8-16 x 3″ for 3/8 5pc bolt)

  • Threaded extraction tool (contact the Access Fund, they may be able to provide the Hurley jr tool)

  • “Funkness” device (typically a short cable that can be clipped into on both ends)

  • Hole/tube brush

  • Blow pump/tube


loosen the cone, remove the stud, and pull sleeve/cone

  • Loosen the bolt and unscrew a few turns, then tap it back in to disengage the cone from the sleeve. Take care to not unscrew the bolt from the cone fully before tapping as you may damage threads or push the cone too far into the hole.

  • Remove the bolt and hanger.

  • Pull the blue compression ring and spacer with the hook tool, if not badly corroded you may be able to pull the sleeve with your hook tool also.

  • If unable to hook the sleeve, cut threads into it with the tap tool. Be sure to regularly turn the tool backward to keep the tap from binding and breaking. Often when you have some threads cut you can just pull the sleeve with the tap tool.

  • Try to cut a good amount of threads to keep from stripping them out when pulling, 1/2” at a minimum.

  • Use your magnet to collect shavings from cutting the threads.

  • Use your draw stud adapter and pull the sleeve with your extraction tool.

  • Screw the bolt back into the cone with a hanger attached, then use funkness device and hammer to remove it from the hole.

inspect and prepare the hole:

  • When reusing a 3/8” hole it is best to enlarge it to fit a 1/2” bolt as the old hole will likely be misshapen and oversized for a bolt of the original size, it is very important to drill the correct size hole for the bolt being installed.

  • If you are extracting a 1/2” bolt, replacing it with an adhesive anchor is ideal.

  • Drill the hole out, clean it and install the new bolt according to the manufacturer’s specifications. This list of tools does not include items that will be needed for installing the new bolt, refer to the instructions for the type of bolt you are placing by clicking here.
