Where can I find a female-to-female hex bit?

Hey there. I have the Pro Tech Toolkit with all its fantastic bits, but the screwdriver sometimes doesn’t give me enough leverage for loads that require high torque. If only I could use an allen wrench, with its fantastic leverage, and a female-to-female adapter bit to put my screwdriver bits onto the other side. That way, I can have the flexibility of all my existing bits but with the extra torque of an allen wrench.

But after a long time of searching, and calling a few stores, I could not find such a product. Does anyone know if such a thing exists? I made a 3D mockup of what I’m imagining, shown below. It’s really simple, but shocking that it doesn’t seem to exist. This one simple adapter would dramatically improve my toolset.

@jordanlees I’d check for a 6mm coupler or similar and use that. Remember that the best tool is the one that you make for yourself. It’s that special tool that nobody else has in their toolbox. I’d go to the hardware store and get a 1/4 “ deep socket (the deeper the better). Then I’d take my well used 4 1/2 inch angle grinder and cut the drive end off the deep socket. That would leave a 1/4” female to female adapter

Hi Jordan,

After talking with the tool experts at iFixit, we aren't quite sure that a product like this is available on the market. I'd be curious to see if anyone else is aware of a similar tool.

Best of luck on your search!

@kristen - I think the idea here is to use an Allen key as a torque amplifier.

One option would be to drill a hole in the driver handle so an Allen key or other small bar could be placed through the handle.

The only risk here is over torque the handle or bit causing it to snap the handle or damage to bit.

I used some air tubing which I pushed over the handle on some tools I have which is another option. At leased here you won't snap the handle.


Hi Dan,

Thanks for the suggestions! I figured you guys might have some helpful ideas. :D
