Review on Boost Chainring Stability and Performance with Zivisk Single or Double Chainring Bolts - Premium 7075 Aluminum Alloy M8 Crankset (5 Pcs) by Craig Waters

Alum 7075, the threads appear to be well cut, fits the sprocket perfectly BUT - 1) for two bolts will fit the hex key is good, fully carved and only about 0.5mm deep (Fig. 1). This provides low wrenching intervention and high probability of stripping. And 2) They're made of copper, not gold! (Photo 2) is one of those screws next to the gold sugino that matches the other gold finish on my bike. So close but so far, I wouldn't recommend.
