### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good quality
  

*by K***I on Reviewed in the United States on August 24, 2018*

Bought these for my 6ku track. Bike after changing the chainring to a vuelta 39t and mounting it on the inside of the crank. The original chainring was mounted on the outside but I switched my rear wheel to a coaster brake so in order to get the chianline straight, I mounted it on the inside as recommended by my LBS. This made the chainring bolts sit in a groove on the backside of the chainring thus requiring shorter bolts in order to even tighten down the bolts. I first grinded the female sides of the original stock 6ku bolts shorter to get them to tighten however for some reason, the 6ku bolts are slightly bigger than my metric multi tool. Maybe they are imperial? Anyway, I rounded one of the 6ku bolts so I required ordering these, even though my diy grinding fix worked well enough. To be fair, I could have flipped the vuelta chainring over, and the bolts would be spaced farther, but like I said, I rounded one so it was unusable. Plus I would like to see the brand on the outside.After receiving the origin 8 bolts I noticed they were higher quality and very hard and dense feeling. Smooth mirror like finish on the chrome. Definitely higher quality than the 6ku ones, and guess what...they fit my multi tool Allen key perfectly. I’m not sure why the 6ku ones are so loose but my LBS guy told me they skimp on little parts to save money rather than using the proper spec parts.Just a really cool trick I did was to sandwich some steel wool behind the female side of the chainring bolts so that when I tightened them down, they didn’t just keep spinning in the slot. It took me 2 hours to figure this trick out. Before that was using all kinds of tools to try and stop the female side so I could fully tighten the male side. Steel wool worked great. I almost ordered a “special” chainring bolts tool. No need. Just get the female side to stay somehow and use grease on the male bolt. For 6 bucks these are worth it and absolutely an upgrade. From what I was told by the bike mechanic and researched...you absolutely don’t want your chainring loose at all. It will wear your chainring much faster and make weird noises. Don’t skimp here. Shipped fast as well.

Old ones were loose and squeaky. Fixed the problem.

    High Quality Steel Bolts, But Too Small For My 1x Setup
  

*by T***N on Reviewed in the United States on January 11, 2023*

These are very good quality steel bolts, but they’re too small for my 1x setup.I’m running Shimano Zee cranks with an FSA chainring and would ideally use chainring bolts with a 6mm nut shaft length, since the Zee crankarm spiders are very thick at over 4mm.The Origin8 nut shaft is only 4mm long, way too short, the bolt threads barely engage the nut, and very little of the nut’s shaft engages the spider. The bolt threads are 6mm long.I still give these five stars, they may be a good fit for a setup with a thinner chainring + crankarm combo.The quality is good and the price is right, and these are made in Taiwan, not China.
