What type of truss rod wrench did Hamer use in the 80s?

Hi everyone,

I have a vintage Hamer Vector (KK Downing) from the mid-80s. I need to adjust the truss rod.

The truss rod nut is similar to Gibson's nut and I have a standard 5/16 hex wrench. Click here for an example of both the nut and hex wrench

The problem is, the cavity of the 5/16 hex wrench is not deep enough to reach the truss rod nut. The actual truss rod doesn't let it reach the nut.

I can go in with a 5/16 socket, but it's thick for the cavity.

What did Hamer use back in those days to adjust the truss rod? I found this on Reverb - https://reverb.com/item/5336610-hamer-usa-original-truss-rod-wrench-all-years - but I'm afraid it won't work because it looks exactly like the Gibson wrench I have.

Thank you so much.

That wrench looks like the one usually used for the "Fender" style guitars.  I use one of the Stew Mac mini tools. they have a nice reach:

Thanks tbonesullivan. Based on the photo in your link, the socket definitely looks longer than a standard Gibson wrench. I'll try that one.

It's the tool that i use on all of my Hamers, Heritages, and Gibson guitars, except for the Hamer Diablos. Those need a different "box style" wrench due to the floyd and neck angle.

I found this type of socket at Lowe’s.  The O.D. on the 5/16”  Is small enough to fit my 2002 Studio Custom truss rod  cut out.  Got a 6” extension to the ratchet wrench.

I have that StewMac set on my bench ... those deeper cup wrenches have another purpose ... they are also great if the nut is so deep on the rod itself that the typical bucket wrench can't bite, or it gets so inadequate bite on the hex nut that you run risk of stripping its edge.
