HFT Quinn Bolt extrators

[KE4AVB]

HFT Quinn 70709 and 59855 3/8 DR SAE and Metric 9 piece sets.

I gave these a try over the weekend and surprisingly for a HFT product they work quite good. The hex I was trying to get out was a heavily rusted 15mm hex M10-1.50. So rusted that the 9/16 extractor fit. I however I had to use a pipe extension on my 3/8 DR ratchet as I didn't have enough strength to turn the screw/bolts. Even 3/8 DR air ratchet couldn't turn them and that is after I used that so called Free All penetrating fluid. This was after it screw soaked for two hours.

Now these are for those hex head bolt/screw that round off enough the normal size sockets and wrenches will slip on. Don't know about completely rounded one.
