Have a board with a deep Tuttle box. Understand there is no problem using a standard Tuttle fin in a deep Tuttle box. I’m looking at a Z fin which has both tuttle and deep Tuttle options. Is there anything to be gained by getting the deep Tuttle option over the standard? Cheers

Deep tuttle is normally for longer fins giving a larger surface area to resist the leverage of the fin.
It also depends on whether you want to use the fin on another board and whether that is DT or not.

As mr Elmo says ,DT will carry a bigger fin like the Z .Fins ...deep Tuttle is stronger ,if your using 42 and over maybe it is worth getting .also using 8,5 sails it feels more firm under foot ,eg ,Isonic ,73 wide has deep Tuttle ,67 wide normal Tuttle .
Patrik 120 litre boards up will usually have a deep Tuttle .Both DT and Tuttle work fine ...

Standard Tuttle works fine in a Deep Tuttle box. Deep Tuttle is mainly just stronger for higher loads like big sails and faster sailing but for most normal use there is no real performance benefit over standard.

Deep Tuttle happened when race boards got wider in the late 90s. Running windward/leeward courses meant that the person who could control the biggest fin often got to the top mark first. Fin sized jumped from 2x to 4x (and ultimately up to 70) as the wider boards gave us better leverage. When the fins got into to mid 40s, we started blowing up standard Tuttle boxes. Deep Tuttle addressed this.
If you are using a fin bigger than something like 43, Deep Tuttle is highly recommended.

Fin is 34cm. As the board is deep Tuttle I’m just wondering if there is any advantage to getting a DT fin e.g stiffer overall setup etc. Don’t intend on using it for any other board.

With a 37 you can think about a deep tuttle. I have some around that size.
Above 42 it is highly recommended.

I've bought M6 x 150 before. bolt shops should have them but if you can wait then $10 for a handful is better than $10 ea
