These are well finished and certainly appear good quality, not sure how well they'll resist rusting, but time will tell.They are absolutely no issues with these and the threads and finishing is great.

These are standard crank bolts they are exactly the same as the ones on my bike which I want to replace as they are looking a bit rusty in the center, these will just look better all nice and shinny.

Seems to fit my bike well. But the center hole is too big. None of my driver bits fit in it.

Lost one of the crank bolts on a ride that must have loosened over time. This has been holding tight so far (I did use some Loctite on it).

Look to be of good quality but only 5 were in the package instead of 6. Hopefully it's just an isolated QC issue.

These bolts are made in Taiwan and are of good quality. I used them on 2 cranks. The black plastic can be removed if your crank arm has thread on covers.

I got a Ride1Up 500 Series pedal assist/ebike a little while ago and the right crank bolt NEVER felt right. I couldn't even use the supposed right tool to fully tighten it. It finally fell off while biking, along with the right pedal arm lol and I needed to get it fixed. I contacted their support and they recommended this. Tried it, IMMEDIATE FIX. I can now FULLY tighten it with the RIGHT tool instead of using a flathead screwdriver and trying to get it as tight as I possibly could.

The original crank bolt fell off my bike and was lost, so fitment was a bit of a gamble for me, luckily these fit perfectly (see measurements below). The bike has inexpensive aftermarket MTB cranks (marketed as Meijun FC-M44) with a square spindle.I was able to measure the remaining bolt onbthe other side and it was "close" to 8mm, so I rolled the dice and bought these. If you have calipers, here are the measurements (I'll also post photos).Bolt diameter (around threaded shank of bolt): 7.77mmHead diameter: 20.34mmBolt length (length of threaded shank): approx 13.6mm

Lost a crank bolt during a ride, this fit the crank arm that came with the BBS02 ebike conversion kit and a 1990s Schwinn MTB. Having the extras stored in my triangle bag gives me peace of mind I can get home safely if this happens again. Thanks!
