number of Repair Cafes and have come across a number of household items
that use them. So far I am the only Repair Coach who has had them at the

Well, Charles, I've had a few screws come out with the SpeedOuts my wife
got me for Christmas one year. But probably not better than 50%, which
is disappointing. Going to try HF left-handed drill bits. I'm sure
there's something else useful when I get over there. There always is!
Oh yes, I wanted to look for triangular screwdrivers; one of the
Christmas light strings crapped out, and the control box has these silly
triangular screws. Only place I've seen them before was holding a
NASCAR HotWheels-sized car to the base. An appropriately sized hex key
fit in there and allowed me to remove it; I got lucky that time.
Unfortunately the Xmas light box is between 1.5 and 2 mm and between
1/16 inch and the next one up (5/64" maybe?).

The best hint for easy-outs (two lies in one) is not to use them at all.off, that also wouldn't break the easy-out when steady torque applied. And
I have never found a screw or bolt that was stuck hard enough to break
now you have an undrillable hard tip stuck in the middle of your screw,
which is still stuck in the part!
Second the motion to use LH drill bits.
