how to remove one-way screws?
I bought a bungalow, with locks on most windows. I can't remove a
window to repair it, without removing the window lock first. It has 2 one-way screws fixing it to the window frame. I can't drill into the screws, as they are a hardened metal. I tried gluing a screwdriver the the screwhead with epoxy resin, but that didn't work. I could attack the lock with an angle grinder, but I know that will make a mess, and require putting lots of protective covering in place first. Any other ideas? |

Or use an impact driver: http://www.kk.org/cooltools/archives/000723.php Sorry, don't see how that would help.

Any other ideas? dremel cut a screwdriver slot, or do it UP till the head snaps off, or use a punch to start it turning, or get a cobalt drill bit and drill the head off, a tiny blob of weld gives something to turn against. |

Assuming the one-way screws are like the ones that I have, it's just a matter of turning the screw in an anticlockwise direction while holding a screwdriver firmly against it so that it doesn't ride up on the sloping part of the slot in the screw. If you can't figure out a way of clamping a screwdriver against the screw, the impact driver should work. You hit the end of the impact driver with a hammer and that is changed (via a system of springs and prawls) into a twisting motion at the screw. The hammer blow keeps the impact driver bit against the screw. |

I just don't see how that actually works in practice, but I'll try it sometime. -- The information contained in this post is copyright the poster, and specifically may not be published in, or used by Avenue Supplies, http://avenuesupplies.co.uk |

I would have thought the bit would just cam out no matter how hard it was hit, given the shape of the screw head I think because you apply the wist at the same time as you wallop the bit into the head. There hasn't been much my impact driver won't shift.! Incidentally is the impact driver the correct name No, it's the 'Oww, ****! bruise-the-thumb tool'! :-) -- the dot wanderer at tesco dot net |

Incidentally is the impact driver the correct name - it seems also to be used for the air and electric ones? Yes. In fact, these tools were known by that name long before the air and electric ones, AFAIK. There was an extensive discussion on the topic here, a while ago. As apart of that discussion, I produced a picture of my ancient one...it's still there... http://www.tavi.co.uk/impact.jpg -- The information contained in this post is copyright the poster, and specifically may not be published in, or used by Avenue Supplies, http://avenuesupplies.co.uk |

There is a socket wrench type reverse driver for these screws. It looks like an S shaped slot in the socket. I received one when I bought a box of one way screws for a window guard installation. I imagine any well supplied hardware store that sells one way screws would have what you need.

The message
from "Bob Eager" contains these words: That's mid sixties too...I bought it to undo the engine casing screws on my Honda CB72...! I knoooow... those poxy cross-heads :( Changed 'em for Allen screws - I suspect most people did...! You often only got one chance to undo the sodding things, so replacing them first time was a smart move. -- Skipweasel Pay no attention to that man behind the curtain. |

The "standard" way IME is to dremel a slot into them - even a pseudo-dremel or big rotary engraver is up to it (though slow) but it's worth buying a decent cutoff wheel. My wife had an engraving tool in her hobby box. It included a carbide disc about 1 mm thick and 13 mm diameter. With that I could make a slot in the screw heads. |
