  3. They are called Clutch type
     
  4. "Clutch head" screws. Google it and find lots of examples.

    My screw heads usually look like whole apples.

  9. When you get the right clutch head tool, and it still strips out, just use a thin cutoff wheel to cut a straight line across the head. Use a large straight blade screwdriver and the screw will come out.

    (1.) Best way to get them out is to put a nut on top and with a MIG welder spot it to the head of the screw. While it's hot, stick a candle next to the top so gravity and capillary action will cause the parafin to lubricate the screw. When cool remove the screw and replace with stainless button head Allen type that is easier to find tools to deal with and won't be a pain-in-the-ass forever (if you use anti-seize when installing). Besides, stainless looks miles and smiles better. (2.) Another way is to buy a hammer driver and the correct size and type bits, only to find after much struggling and a lot of cursing, because of the design this just wallows the head out. When this happens, refer to (1.)

    Many Holley 4V secondary metering plates are held on by six of them. Snap-on (and others) sell a ratchet wrench bit attachment to remove them.
     
  20. I've heard these referred to with many descriptions, but apple core is a first for me.

    My 51 Ad still has most of those clutch head screws. The only ones missing are the ones for the door striker and the transmission cover. I like them and reuse them because of the originality and because they are not as common as they once were.

    The bad thing about real clutch head screws is they are knurled under the head. The serations dig in when installed and don't want to let go. That's why the factory used them, but it makes them a bitch to get out.

    Ahh.. this made me think of being a kid again, I lived in a mobile home and theses things were everywhere. I would accidentally drop things down the floor registers and never had the correct tool to remove the screws.

    That's a first. I've heard those described in a lot of different ways, but never as an "apple core". I knew what you meant before I opened it ! Good one.
     
  27. They're an option on many military spec fasteners.
     
  28. I've never heard apple core to describe them either, but I knew what the OP was talking about before I opened the thread. (and I knew they'd be on a chevy also.

    we used fine valve grinding compound or clgate toothpaste on the bit like when you take off a phillips head so the screw driver catches the edges by filling in the gaps and the abrasive action of the paste . also wacking them with a ball pein before you try to loosen them helps break the bite too , I remove and replace them with torx or allen buttons . my haters are the square head drive ones
