6 mm Allen wrench

[Donald]

I need a 6 mm Allen wrench that I can use to tighten a cap screw with 2 fingers (that I cannot see). Not a thumb and fingers. Just 2 fingers. It cannot be much bigger in diameter than the cap screw.

The goal is to turn the cap screw with this tool until its finger tight then use a regular Allen wrench (with much difficulty) to fully tighten.

Two fingers cannot seem to turn the cap screw.

The closest I have thought of is a 6 mm Allen socket for a 1/4" drive. Try to turn it with 2 fingers. No 1/4" drive ratchet attached. Just the socket.

Cut off a cheap Allen wrench.

As mentioned by jhellwig, cut off an allen wrench and then wrap masking tape where your two fingers are going to grip it. As much tape as can be applied because the larger the dia of the taped section the easier it is to turn

If there is enough room. try a socket Allen key?

I had the same problem with a single handle kitchen faucet that had worked loose and the screw was recessed so I couldn’t even see the screw due to the backsplash. A tiny Allen wrench did the trick though it took some time, turning it 1/4 of a turn at a time.

If I understand this right... would skateboard tape around the 6 mm Allen socket help?

 

[Donald]

Maybe a 1/4 socket Allen wrench where I grind some lines almost as it it was knurled.

cut off a piece of the allen screw,then get a section of rubber hydralic hose ,stick the allen wrench piece in hose.

Look at the hazet 1/4 drive hazet monoblock sockets.

How about this? Ratcheting 1/4 female hex on one end, 5/16 on the other. Plop in whatever bit you need and there you go. This particular one is Matco, EZ Red has one with an s shaped handle that is very useful. Check out Vim also.

The most I can fit is a shift 6 mm Allen wrench and get less than 1/4 swing.

 

[Donald]

What I need is a 6 mm short Allen wrench with a ratchet embedded within the Allen wrench.

Look at the hazet 1/4 drive hazet monoblock sockets.

I see the knurling. Picture on Amazon looked gold colored. For $17 I assume gold plated. I ordered one.

I've got a set of CTA stubby hex insert bits that have a 12mm hex drive size and retention ball that fits tight into a box end wrench or socket. I picked up the torx version to do a water pump job in a super tight spot and was so impressed that I grabbed the hex set too.

Sounds like you already found a solution, but they may be worth a look anyway.

What you need is a chapman set.

So it arrived and while I wish the knurling was more pronounced, it may work. Also possible with a 1/4" universal joint and a 1/4" ratchet I could use the ratchet to loosen or tighten the cap screw.

My original goal was just to use this 6 mm Allen socket to give my fingers more leverage when loosening or tightening the cap screw. But a short Allen wrench to do initial loosening or tightening.

Rubber band around the barrel?

 

[Donald]

Rubber band around the barrel?

Maybe. But there are clearance concerns. Cannot be much larger in diameter than the cap screw.

Then get a 6mm ratcheting wrench, and cut a stub of a ball-end Allen to use as the working part.

This is the CTA insert bit compared to a regular sized 3/8 6mm socket. It's 13.5mm at it's widest point and 20.15mm long. The shiny thing is the detent ball that holds it in a wrench or socket.
