    These are the bolts for Cali Raised tailgate light mounts. There are two inside the bed.

    They're 10 mm. I can't figure out what the official classification is, so I can order replacement security bolts with fancy heads.

    Any ideas?

    when you say 10mm I assume you mean that is the size of the head?

    The are likely M8 if so

    I bet m6 like all other 10mm bolts hex head bolts (socket size)
    Probably 20mm length but it's hard to tell using an imperial ruler to measure a metric bolt.

    Take it to a hardware store - they have thread gauges

    That looks pretty small to be a 10mm unless you're Andre the Giant; I'd quicker think 8 or maybe even 6, depending on the size of your hands.

    Regardless, any reputable hardware store will have one of these gauges that you can use to determine size and pitch.
