Proper terminology for a "screw"

[T56 Impala]

I need to take apart a battery for my Drill. Actually 2 of them. The screws holding the two halves together look like Allen head screws with a spike in the center. They are tiny screws and I need to buy a tool to take it apart. What are these screws called? And where do I find a tiny driver that small?

Those are security screws and they didn't intend by you to mess with them.

 

[Ed_EOD]

They are called security or tamper proof hex. If the company really didn't want someone opening it, they wouldn't have used screws. They just don't want every joe-blow with a Phillips screwdriver to do it.

Easy to find the right tip at any real hardware store.

By 'Real', I mean anywhere besides Home Depot or Lowe's

tamper proof torx?is the hex more like a star

 

[el tanque prohibido]

There's tamper proof hex and tamper proof torx. They both have a pin in the center. Look at Apex, Bondhus, and Zephyr for the tools.

Thanks! And I know, they did want just anyone removing them. If Milwaukee didn't make such crappy tools and batteries, then I wouldn't need to take it apart! I'm hoping I can find enough good cells in the two bad batteries to make one good one. If not, then I'll just toss the crappy drill in the trash. I have more money in batteries than I do the drill now. It would be nice if a battery would last more than one year.

I spent a LOT of money on this drill. It was over $250 new and I have not been happy with it at all. My father, who uses his drill dang near every day, has never had a bad battery or any problems with his over the last 5 years. His is a $29 HF drill. Go figure.

I think craftsman uses a tamperproof T10 torx

If you use a small pin punch and a small hammer strike the center pin it will break off than you will be able to use a regular driver to remove the screw.
I have done it many times in the past the center pin breaks quite easy when struck from the side.
