I'm trying to deal with small Torx screws on a drive case. They're
about T8, maybe T7. Tough to tell cause the screws are 'pre-stripped.' In other words, there's not much edge for a Torx driver to grip them. They almost look like rounded allen-head screws. I'm trying to figure out how to deal with them. These are not the tamper-proof variety, so I don't need a hollow-point Torx driver (if they even make them that small). The first thing that occurred to me was to place a small Torx driver in the holes and tap the end lightly with a mallet. That could do more harm than good though, as this looks like very soft metal. It's also a working disk drive case, so I don't want to damage the drive. I could try a tiny screw extractor, but the risk is that it wouldn't work and then the remainder of the screw would really jam things up. Any other ideas? |

Small drill bit or grinding bit in a Dremel (other small drills are
available) should allow you to take the head off. If it's a drive, chances are that once you've taken the head off the screw, the actual shank will unscrew without any trouble because there won't be any pressure on it any more. It's not as if it will be rusted in place, or if it is, you're probably wasting your time anyway. HTH Mike. "_ZZ" wrote in message ... I'm trying to deal with small Torx screws on a drive case.

You mentioned its a working disk drive - why do you need to disassemble its case? Such operations are strictly for the experts in a cleanroom environment as even a tiny spec of dust getting in can ruin a HDD. If on the other hand you're referring to screws which hold the drive in the PC case/cage then a dremel with a cutting disk in it could be used to cut a groove in the head to suit a flat blade screwdriver.

Use a small (3/32"?) left-handed drill bit and start drilling out the screw *very* slowly with a variable speed drill. Once the drill bit bites into the screw, it will back the screw out. I've done this will several very small computer philips screws -- I don't know why torx would be any different. Best regards, Bob |

Find the closest shaped bit you can that's a little oversized. From your description it would be an allen bit. Since that is not a complex shaped pattern you can probably replicate it with minimal effort. Take a fine file and reduce the bit just enough to fit with minimal-to-no force to insert it. |

I would use the thin cut-off wheel on a
moto-tool to cut a slot across the head. Then use a flat screwdriver. If the screw is a flat head, you may have the use a small "easy out." as others have suggested.

'Pre-stripped' means that the original Torx (if that's even what they are) have barely any edge...very rounded, almost like an allen indent, but even rounder. They obviously didn't want people messing with their drive case. I've seen tons of cases like this, and this is the only one that uses such a bizarre screw. Also, the screws are slightly indented. Metal from the enclosure forms a shoulder around it. But the idea of sawing a flat-blade slot may work. I may be able to get a small blade in there. Then I should probably find replacement screws. They'll probably be some odd Martian thread. |

You might try a "worn down" cutoff wheel. When worn, the diameter can be as small as 3/8". Not knowing the exact geometry of the drive, it's hard to know if this would work. You still have to physically get the tool in the area. BTW, use safety glasses ... these wheels can fly when they break up and they WILL break. |

This epoxy idea may work, but it seems you left out a few details as a hole filled with epoxy isn't much easier to get out than one with an odd head pattern. I have used epoxy before though, sometimes with success and other times it just tore up the epoxy. This was using JDWeld, do you have a better suggestion for a stronger epoxy? I'd also thought about saving some aluminum filings the next time I did any metalwork (non-computer related, just fine almost dustlike Al) then mixing that into the epoxy to fortify it. I still like my idea of filing down a bit because if you ever come across that pattern & size again you'd already have the bit. |

Sears has screw extractors. Get the kind for screws that cannot be drilled - the one that fits over the head of the screw and has left-handed protrusions inside which grip the screw. Go easy or you will snap the screw off. You should soak the threads in anti-seize liquid like WD-40 overnight to help ease the unscrewing. |

SInce the heads on these screws are probably protruding above the casing, a high-tolernace pair of needle-nose pliers might be used to turn them. A small pair of vice grips can also be used. Other alternatives include using a high acid silver solder plus a clean torx bit, soldering the torx bit into the screw head (Or at least making an impression of the screw head even if they dont' mechanically join. I would be afraid of burning something. He might try JB Weld overnight epoxy. That stuf is strong enough to repair an engine block I have to wonder what gain there is in getting these screws out though, if the drive is scrap anyway and they can't RMA it, then maybe using a drill press to drill the head off is enough. They aren't going to RMA a drive that has obviously been tampered with. |

Naw, the entire drive shell is a pretty massive 'sink... all you have to do is get the bit above the melting point of the solder and that can even be done before it's inserted into the screwhead. You still have to heat the screw at least to the melting point of the silver solder for it to stick. |

This of course won't work if the cutoff wheel is too thick for the tiny screw, but the lightest-duty cutoff wheel is pretty thin. I've used this method many times for larger screws - works great. If the screw is too small you can use an extractor like the one at Sears. It fits over the head and has left-handed protrusions inside to grip the head. |

Yes, but if the case is metal that shouldn't matter. Heating and contraction (after cooling) might even help to free it if it's stuck in a dissimilar metal case. It may not be necessary to heat the screw though, That's how I usually free up screws - heat the thing the screw is in. if the bit with molten solder is inserted in the screw head, the solder will still cool to the shape of the screw head even if it doesn't adhere to it... and it was one of the reasons I suggested silver solder (or something else other than tin/lead) as it is tougher than std tin/lead. I have never tried that. It may just work. If so, then you do not need to heat the screw - just melt a drop of silver solder above the screw and let it fall into the head of the screw. |

See where I'm going? I think the moral of this endless saga is to RMA the bloody drive and not try to take it apart. Another lesson to be learned is that hard metal screws seize on aluminum so you must lubricate before trying to unscrew. That's what they make WD-40 for. |

See where I'm going? yes but I have no idea, I"d already deleted the rest of the thread and too lazy to go hunt it down again. In any case, it should not damage a drive as those are encased in metal, it'd be a problem if the screw was in a plastic casing though I'd be surprised if the screw was very hard to get out of a plastic casing so I suppose I'd assumed metal. |

Personally, I like the idea of epoxying something to the head of the screw, rather than using heat. Whatever you decide, be sure to let us know what you came up with... None of us are ever too old to learn something new. Good Luck! Notan |
