    Default Not seen a screw head like this before.

    Hi Guys,
    Does anyone know what this head type is called and/or when I can get a bit for it?
    Its on our security sliding fly wire door. It looks like its stopping me from replacing the door rollers that 'she' wants fixing.....

    It must be a 'security' type as it has a nub in the centre. A Clover Bit?....lol

    Phillips head with a security/anti tamper tang.
    Not super common in Australia, potentially difficult to source locally.

    Thanks. 'Philips' didn't even enter my mind, but looking at it, it makes sense.
    Maybe I could drill a hole in a philips screw driver...will see.

    I have successfully used horseshoe head security driver heads (more readily available) on those screws. I had to lightly griund the sides on an angle so they fit the slots.

    However you get it out, I can pretty much bet it won’t be included in the reassembled door

    Not sure what size your screw head is, but here's a locally available #3 Phillips tamper resistant bit:

    Don't really want to do that. They are visible and don't want to change them out, if I can help it.

    They make them in No2 phillips as well, just search for GFB-308-B on that same site and it will come up.

    I ran into a similar problem a while back, except mine was a security hex key with the centre post, I used a hammer and pin punch to snap off all the stubs then used a regular hex key to undo them.

    My Rhino roof racks also have them, but I was a bit more gentle and drilled out a hex key on the lathe for those

    If You have Harbor Freight over there the bit is included in their tool bit set.

    No Harbor Freight here, neither the store itself, or much freight happening on harbours.
