碳纖維套筒用不鏽鋼鉚釘（單獨販售）

The machining on this single rivet is precise enough that it seated flush into the carbon fiber sleeve without any filing. It took all of ten seconds to pop it in and finish my repair.

I needed exactly three of these to finish reinstalling my carbon sleeve after swapping the muffler packing, and each one pressed in cleanly with no binding. The stainless material gives me confidence it won't corrode like the old ones did.

The rivet seated perfectly into the carbon sleeve on my first try, and the stainless finish looks clean against the weave. Nice to have the exact single-piece option instead of buying a whole kit.
