Hex Key aka Allen Wrench for Hastur RDA
If you bought your Hastur somewhere else, or lost your allen wrench altogether, these ultra-high quality replacement 1.5mm hex keys are a perfect match for those surgical steel grub screws.
We currently source the longer, 3" versions to give you the best control, and because they work pretty well to wrap 1.5mm coils in a pinch.
Heat-treated CrNi alloy steel is then plated for rust resistance. The manufacturer claims you can achieve up to 20% more torque without rounding the edges. Made in U.S.A.
