    broken screw extraction

    Anyone know of a way to remove a broken screw? I snapped it off flush to the surface.. so a nice dremeled slit & screwdriver won't work. & I have had no luck with the extraction bit set I have. I need my backseat back in my rover. Any clever ideas?

    a reverse drill bit might work.

    Ez out? There are two ways of doing it.

    If you have some of the thread exposed there are a set of reverse sockets that fit over the head/shaft, and as you turn the ratchet - in the loosening direction, it bites on the thread/head/or part of the screw thats exposed and pulls it out. The other option is and ez out, that has a reverse thread. This involves drilling a hole in the screw/bolt, then inserting the reverse threaded bit, and as you loosen again, it bites into the middle of the bolt, and pulls it out.

    Options depend on the amount of bolt/thread/thickness etc...
    for exposed threads - stripped bolt heads

    For thicker bolts - drilling and extracting

    These are just the idea....you can find this stuff at any hardware store thats worth 10cents.

    That happened to me also.I just used a self tapping next to the broken one.My seats are out most of the time but when I do have them in they are just about self supporting.Good luck with the screw

    I am otherwise defeated.. I might just do that. I did notice that the screws do poke out from under the truck some.. I might be able to get them out from the bottom, otherwise it will have to be a self tapped job.. Thanks for the suggestions!

    you need a drill bit called tungsten carbide you can get it at true value hardware and buy the extractor bit and handel. i've been through a lot of broken bolts and nothing else really works. you'll need to dril in the center down about 1/4 to 3/8 depending on the size of the bolt. if all else fails get a biger drill bit and make a new hole and thread it. good luck

    I highly recommend using a left hand drill bit to drill the hole for an easy-out. Often just drilling the hole backs the screw/stud out. The act of drilling generates enough heat to cause it to come free and spin out.
