Armstrong 12-972 Dis-assembly

[bigphillystyle]

Does anyone know what size allen key is needed to remove the 2 screws on the back of the Armstrong 12-972 ratchet?

I have tried metric and SAE and I cannot find a fit. Does this require a non-standard size?

This precision screwdriver set will have all the bits you need. I've used it for disassembling ratchets, cell phones, led fixtures and more.

The bits are made from CR-V and are cut pretty well. I have numerous different precision driver sets and for the money - this set is the most complete and the best value.

Oh, and the bit you're looking for is probably a really tiny "torx" bit. My 1/4 drive ratchet required a T7, which is the reason why I bought the above kit.
