Screwheads, was: 5" floppy?.

Flat blade? Those are not a problem if you use the right screwdriver. Unfortunately, you can't buy the right screwdriver at the hardware store, or from most tool suppliers (such as electronics tools shops). All they sell is wrong screwdrivers -- you can recognize them by the fact that the blade is tapered (wedge shaped). Those will "cam out" and damage the screw, if you need any significant torque. Correct screwdrivers can be found in one of two ways, depending on the size you need. For the small sizes, get watchmaker screwdrivers. For larger sizes, get gunsmith screwdrivers. Both have hardened tips, hollow ground so the point that fits in the slot of the screw has parallel sides, not tapered sides. With those you can work those screws without damaging them, even if they are quite tight. I have a nice set from Brownell's that I use all the time. For watchmaker screwdrivers, be sure to get the hardened ground ones. You can also find crummy ones, not just at Radio Shack but also at more expensive outlets like Jensen Tools. I think I got a set there branded "Moody" (?). The bad ones are plated, as opposed to having the blue-gray color of hardened tool steel, and their tip shape is only a loose approximation of the correct one. paul
