Agree that Torx is a lot better than Phillips. But it was no fun at all to
confront a Compaq full of Torx many years ago. I have since overcome the Torx obstacle with a very nice set of Torx, Phillips, and flat blade screwdrivers from Sears. The screwdrivers are perfect for work on laptops, hard drives (ever remove a hard drive PCB?), and other teeny tiny stuff. The flat headed screwdrivers are the right size for prying off the flexible piece of plastic that covers the area between a laptop keyboard and the LCD screen. Highly recommended and inexpensive. There I go again, giving away trade secrets! Darn! ... Ben Myers On Tue, 07 Oct 2008 06:57:31 -0400, Ron Hardin wrote: Ron Hardin wrote: So, plan B is a screw extractor. Any hints on the best type to try? A 3/32 drill bit fits in the removed-screw holes, if that indicates the size involved. Very very short screws. I don't know that you could drill into them without drilling right through them. I remember from the WSJ in the 70s or so, an article on Phillips screws, that mentioned they were _designed_ so that the driver would auger out when tight, to prevent overtightening by automatic screwdrivers. Chrysler used them on windshield frames, is what I recall. I see Wiki has ``Phillips Has slightly rounded corners in the tool recess, and was designed so the driver will slip out, or cam out, under high torque to prevent over-tightening. The Phillips Screw Company was founded in Oregon in 1933 by Henry F. Phillips, who bought the design from J. P. Thompson. Phillips was unable to manufacture the design, so he passed the patent to the American Screw Company, who was the first to manufacture it.'' Why anybody would use these today is a mystery. There's a thousand better designs. |

Dell, along with other brands, uses SOMETHING on its laptop screws to get them
to seat perfectly and hold tightly in place. Often, when I remove a screw, there is a greenish residue on the screw threads. But I, too, have never met a laptop screw that I could not unscrew...

Sam Molex invented them?? Actually, the advent of SATA drives means that the
power and data cables are easier to remove than stinking 4-pin Molex that has been around forever, and, for that matter, its companion 4-pin connector for floppy drives and similar devices. There are tight fitting connectors and tight fitting connectors, but 4-pin 12v-5v Molex does beat them all...

Often, when I remove a screw, there is a greenish residue on the screw threads. But I, too, have never met a laptop screw that I could not unscrew... Ben Myers the residue is threadlocking compound ie Loctite. From Wikipedia.... Loctite's threadlocker products come in different strength grades, to suit the particular application. Blue Removable No. 242, 243, 246, 248, 2432 & 2440 - Used for things you may want to unscrew with minimal hassle. It cures into a brittle, glassy bond that takes one good twist to break, but removes cleanly after that. Recommended for use with valve covers, water pumps and oil pan bolts. Red High-Strength No. 271, 262, 266, 268, 272, 277 & 2760 - Used on things that you don't want to take apart for a long time. It requires heat from a torch or iron (to 250° C) to loosen its grip. It cures into a thicker, sticky bond that holds up better against vibration and shocks. It is typically used in mechanical applications such as nuts and bolts in cars, motorbikes, snowmobiles, and watercraft. Green - penetrating grade No. 220(blue), 290 & 294 - Used for parts that have already been assembled. Green No. 290 is commonly used to bond a bearing to a shaft. Due to its low viscosity, capillary action wicks the solution between the shaft and the inner race of the bearing. Purple - low strength grade No. 222MS & 222 - Used for set screws. For Plastic threads - No. 425. - Used for small plastic threads. I'm surprised that the laptop screws use the Green compound as Blue would hold for most hardware applications. However a small amount of heat (soldering iron tip) applied to the screw head will soften any of the different grades. I've used this stuff for years in many different applications. Another thing to try is to replace and tighten the screws that you have been able to remove and then try to loosen the ones that are stuck. The pressure of the assembly against the screws can increase against the last few after most of the others have been loosened...making them hard to turn. |

Hi!
There I go again, giving away trade secrets! Darn! ... Ben Myers However, your advice is right on the money. Having a good set of tools to "do things" with computers is money well spent. I didn't realize how true that was until I headed to Sears and put together my dream computer toolset. Now everything I need from scissors to T4 drivers is in one place. I also keep some spare power buttons pulled from scrap computer cases in there. For those wondering what they might put in there, here's what I put in mine: A roll of wire Small hot glue gun and glue sticks (already had this from my Dalls clock module rework--see http://greyghost.mooo.com/ds1387rework/) Precision screwdrivers in long and short shaft Small precision Torx drivers. Household scissors A box cutter with retractable blade A card that accepts a 2.5" hard disk and lets you plug it into a PCI slot for power and a 40-pin IDE cable for data. Wire splices Larger screwdrivers in short and long shafts A knife Electrical tape Various and sundry picks and hooks All kinds of small pliers and wire cutters A multi-use wire stripper, crimper, cutter, etc A telephone plug crimping tool Screws for various things with various heads A ratcheting multi-bit screwdriver. A so-called "spudger" for taking apart certain iPods and other Apple creations like Powerbooks. (This I made out of a "steak pick" from a restaurant.) I am thinking of putting a small roll of solder and a soldering iron in there, but they don't see much use. William |
