Machine screws and untapped holes
Am I the only one who got the impression on the "Where to buy machine screw
assortment" thread that the OP was only talking about using an untapped hole to jam the end of the screw into (or perhaps holding it in a vise) as he evaluated how easy it was to twist the screw apart? It sounds to me like he was only testing the screws, not trying to put something together. He seemed to think that he needed screws stronger than what he had and asked if anyone knew where to get stronger ones. I too was confused by the postings on both sides until I got this idea and now it seems a lot more logical. Don Young |

Don Young That's the impression I got as well Don; someone who KNOWS where the problem is without debugging the process. Martin -- martindot herewhybrowat herentlworlddot herecom |

He never actually said he was trying to screw the screws into an unthreaded hole, but he did at one point hint at it. He had heard that it was possible to use a screw in an unthreaded hole in aluminum. He never said what type of screws he was using, however, other than that they were from Lowes. There are, of course, special machine screws (type F) that will cut threads in aluminum perfectly well, but he never said that he was using those. He also hinted that a tapped hole would not work for him because he needed something with a tighter seal. Only he knows what he was really trying to do. His replies pretty quickly turned into those of a jackass. Not worth worrying about him or his screws. Although some more recent posts here do show a kinder and gentler - and perhaps apologetic? - John Doe. John Martin |
