No Good For Thorn Tandem Chainring Bolts

I recommend this product
I wanted to lower the gearing on my tandem by fitting a smaller rear chainring. My Park Tool chainring wrench didn't fit. I bought the Shimano tool, but it was no better. It probably works well on the bolts it is designed for. I phoned SJS to check suitability and was told it would probably do the job - but there was some uncertainty.
