Suitable allen wrench for P-bass with neck heel truss rod adjustment?

[billgwx]

My P-bass truss rod adjustment is at the neck heel. There is a space to reach the truss rod without having to remove the neck, but it's too small for any of the Allen wrenches I have at home. Where can I find a suitable Allen wrench? The ones I see at the StewMac web site don't look like they could pull it off, but I could be mistaken. Thanks!

This works very well for my 2011 American Standard P--much better than the t handle wrench that came with the bass. I use the 3/16". Other guys make their own by cutting a 3/!6 allen wrench just past the bend.

that's what i did, with a few minutes of hacksawing, followed up by some cleanup on the belt sander; makes it easy to tweak the neck of my '96 american standard P.

You need this or something just like it:

All it is is a straight Allen tool with a ball end and torque grip.
