    Snapped off a bolt head...

    Last night while under the ski I snapped the head off an intake grate bolt I was really surprised that it snapped so easily, all I was doing was snugging it down... What is the best way to get the bolt out now?? Anyone done this before? Suggestions?

    Yep done this more than once. Drill it out, and get an extractor set. If that doesnt work, drill it out and re-tap it to a bigger size and get some new bolts (Be careful to get a bolt with a head small enough to fit in the mounting hole and be able to put a socket on it!!!) Just my $0.02

    ...another option, But only for someone who is proficient with drill bits

    I use lefthanded bits at the shop on bolts that are not badly crossthreaded or rusted in place. Usually you have to drill all the way through the bolt, but when it hits the end, it unscrews itself. The downside is if you arent straight when you drill, you go into the threads.

    YEP! This happend to ME! and this is the ticket.Left handed drill bits. NEW SHARP ONE! It will bite and spin it out, If you have a Keyless chuck on your drill make SURE you tighten it with Channel locks or get it real tight.

    Yellow, These are great sugestions as a last resort.

    How much of the head came off?
    If there is a nub left the easyest way to get it out is to remove the grate, clamp a vice-grip on it real hard, heat the nub with a hot soldering iron and back it out with the vice-grips.

    All of it... actually is snapped a little way into the bolt, meaning there is a head and a little bolt that broke off...
