Which concealed fasteners for accent ceiling?

[zanemoseley]

I'm doing about a 400-500 sq/ft cherry accent ceiling in my basement. I'm wanting to install them like the fancy ipe and other exotic pre-grooved decking. Already got a stack of cheery and can route my own groove. Will be leaving about a 5/32" gap to accommodate the screws used with the hidden fasteners. I like this route over T&G or shiplap because I'll be able to remove boards if needed to access the utilities at some point. I like the look of the Ipe Clip but they're close to $1 each after shipping and tax. Would really not like to spend $500 just on fasteners.

Anyone got any suggestions for a basement cherry ceiling attachment method with 1/8"-1/4" gaps that allow semi-easy access to utilities above if needed?. Guess I could make some large tile assemblies about 4x4' then install them with trim screws through the gaps.
