Self tapping screws
A couple decades ago, I ran across a handfull of self-tapping screws. They were like sheet metal screws, but with skirted hex heads. These were about 1/2" long and 1/4" dia. I'd seen them used with a special head on a drill motor, it having a hex chuck that would ratchet when the screw bottomed out. What amazed me about these was the fact they where not only self-starting AND self-tapping, but they where pretty damn hard. In experimenting, I discovered they tapped and screwed into an old BSA motorcycle frame like it was soft pine. I now find myself in need of something like this and was wondering just what, exactly, do I ask for when I go down to the hardware store. nb |

If you search Tek or drill point screws, you'll probably come across the exact screw you have used. TDD |

Cheaper by the box of 100 but that depends on how many you need. I use the #6 x 1/2 to drill the hard coat on plaster. Cheaper and safer than drill bits for the same job. Of course my price is based on a bag of 500 at one time so YMMV. Colbyt |

I've seen that kind of thing at Lowe's and Home
Depot. I call them hex head self drilling screws. They have them in small packs, or boxes.

Is that a special type, or do they all do that? I'm looking to use the screws to punch through and lock up the louvre adj linkage on a forced air heat register, which is stamped steel. Thnx. nb There are different types of screws: The self-drilling and self-tapping. One simply brings the point of the screw to a fine point with the threads going all the way to the end. They're good for sheet metal or most sheet products. BTW, your motorcycle or whatever it was is likely to be soft steel; it has to have five to it in order to not crack or break upon hard hits on the screw during riding. I know the frames on Harleys and Hondas are soft steel, depending on what part you'\re looking at; like the frame itself, front fork, etc.. The other type, the threads don't go all the way to the point. However, the point is shaped almost like drill bit and some are fluted, to pull the debris out, within reason. The length of the drill-looking part is the depth of steel max it can be used on. All kinds of sizings are available. See http://www.imperialinc.com/items.asp?item=8901330 for a sample pic. Unless I'm doing sheet metal type stuff, I like those the best because it pre-drills the hole for istelf all the way in, the larger threads providing the actual holding power like any other screw. Either type should work for you. HTH, Twayne` |

I have found that the screws available at HD (Western States Mfg?) have slightly shorter heads (~1/32 or so) than the ones I've gotten through McMaster. These slightly shorter heads do not engage in the my hex drivers as well as the McMaster ones.
