Another couple of options.
[a] couple of lift-off hinges one side and toggle clamp other. Dearer.
fixed studs to frame and wingnuts to compress the seal. Cheap as chips.

Yes , I'm not a timber framer by profession but I have built a workshop and currently cutting joints for a garden room/office thing. 6x6, 6x8,6x10 oak timbers.
My first couple of pegs were too tapered and didn't pull in enough. Replaced with others and fine since.
If I'm going through 6inch beam...
Only the first part needs to be Tapered, to find the Off-set hole. The rest should be tight-ish in order to keep the tenon pulled in.
Not too tight or danger of splitting the beam. Kris Harbour has a bit of a Youtube episode about pegs that he had to adjust because the pegs he bought were not...
I have "stamped" metal plates. The letters / numbers are raised slightly (like USA, ?). Brought them because other drivers keep breaking the perspex ones which is a fail. Had several MOT's all ok.

I've seen some pictures/diagrams that showed the use of two osb/ply pieces to screw against. Inside and outside strips leaving full insulation in between.
