Hi. Does anyone know the correct allen key size for the truss rod please? I've searched online but without an answer.
Apologies if this is in the wrong place.

my TE52 ia a couple years old, but i doubt that HB has changed the trussrod. so, yes its 4mm.
the FLT is 4mm also.
same for the DC junior double cut.

Hi, I don't have a TE-52 but I do have a TE-20 and that came with a standard 4mm Allen key. There are a number of forum members with TE-52s so they may be able confirm that it takes a 4mm one as well. Alternatively, you could send Thomann an email. They are normally pretty quick at answering queries. Thanks for the replies. The guitar was bought in December 2019, Roswell pickups. I have no idea whether anything else changed from previous years.
I've tried a 4mm, too small, a 5mm is too large, of course, I don't have a 4.5mm to try. Is it possible the key is imperial? Good idea to email Thomann, I'll do that tomorrow.

I doubt it's been rounded off, the 4mm key was too small to begin with. Strange.

I would be surprised if the truss rod socket is imperial but stranger things have happened. You could try a 3/16" Allen key as that equates to 4.7625mm. Thanks for the reply, but 3/16 is too big. Had a look down the throat of the socket using a magnifying glass and bright light. As far as I could tell, it wasn't rounded. I'll find a 4.5mm key from somewhere and try that. 11/64 equates to 4.365mm, doubt there's an allen key in that size! I'll see what Thomann say. This is the first time since buying the guitar I've felt the need to adjust the truss rod, so if there is damage to the socket, it came from Thomann like it. Could explain why no truss rod key was sent with it. But that's pure speculation on my part.

If you have access to some form of bench grinder/linisher or a dremel. You can carefully grind each side of the end of a 5mm Allen wrench and create a chamfered wrench. This allows even a worn truss rod socket to be turned.
Stewmac sell this type of Allen wrench but they are expensive. Far cheaper to make yourself iif you have access to tools.

An update. Messaged Thomann, they have kindly sent me a 4mm allen key. It is too small. I'll message Thomann and see what happens.

You could take an imprint of the hex by pressing a cylinder of Plasticine or Blu-Tac into it. Even some bubble gum at a push. See what the shape is and measure it. My thought is that it is damaged in some way, or else it is very deep seated and the wrench isn't reaching into it properly. Try the longer end.
Thanks for the suggestion, sorry I'm replying so long after. The guitar was posted back to Thomann yesterday. I think you're right, I think it was damaged when being set up prior to original delivery and no hex key was included.
