i bought these to use on sram force 2x cranks that have been 1x for the past few years. they work well enough, but be sure not to over torque them. the alloy is pretty soft, and the head will just tear off if you're not careful (like i was). it seems like 7-9 Nm is the max for these. unfortunately, i've had creaking in my drivetrain since installing the bolts, which may be due to some play. otherwise, they're decent and shouldn't corrode.
