Re: One Of The Best Hints I Ever Received
By coincidence, I taught a neighbour this trick yesterday. He was changing the rechargeable cells in a set of outdoor lights, the housing was of course cheap plastic held toghether with self-tapping screws.
Odd thing is, he'd been a machinist making milling cutters in his younger days, so he was hardly a stranger to using tools. |

Re: One Of The Best Hints I Ever Received
The method sometimes doesn't work if the final lead out or lead in part of the thread on a nut or bolt is slightly malformed/bent, it will then have a tendency to tilt the nut/bolt no matter how much you back turn. It's all down to 'feel', and again this is conquered by experience telling you what's happening and knowing how to overcome it by how you position the nut or bolt. Sometimes I will file/chamfer offending parts to enable better initial take up.

Re: One Of The Best Hints I Ever Received
-I wasn't aware of the JIS (Japanese Industrial Standard) type of cross-head screw until recently, the screw type HOPEFULLY being identified by a dot on the head (same idea as the tell-tale extra radial lines on a pozidriv screw head)
It seems that a JIS s/driver may engage with a Philips screw, but a Philips s/driver will bottom out in a JIS screw before the drive faces have engaged. Owners of Japanese motorcycles have known about this for decades, but i think some of the screws i have managed to chew in the past could have been JIS (and i just blamed it on bad manufacturing) Dave |

And if JIS screws won't slacken off using what screwdrivers you have, use a set of side cutters (90 degrees to the screw head) if there's room, worked every time for me.
