فولاذ

Swapped out the worn chainring bolts on my road bike and these steel ones felt solid the moment I torqued them down. The black finish blends right in with the rest of my crankset, and nothing has loosened after a few hundred miles.

Swapped out my old rusty chainring hardware for these and the black finish looks sharp against the crank. Threads were clean and they torqued down without any stripping. Solid little upgrade for the price.

Bolted these onto my road crankset and the chainring sits rock solid with zero play after a few hundred miles. The black finish still looks clean and the threads engaged smoothly, no cross-threading at all. Exactly the dependable hardware I needed.
