Didn’t fit my chain ring
These were slightly too long to tighten down on my chain ring, not necessarily Pyramid’s fault. I added some washers and BOOM, I’m in business. Work fine.

Better than alloy bolts.
Got these after stripping out several alloy bolts. It’s not like these weigh that much more than alloy, so unless color is more important to you than durability, go with steel bolts over alloy.

There is nothing worse than the annoying creak of a loose bolt so I was looking for one that I could really tighten up if you know what I mean. I put these bad boys on to stay. Didn’t use a torque wrench or anything, just cranked them for all I was worth and didn’t strip a single thread. If you need some new chain ring bolts, and I am guessing you do since you wouldn’t be here looking at chain ring bolts if you didn’t need them, then look no further because these are the bolts for you!

These worked great and I’ve had no issues so far
I bought these to support my single speed conversion of a 1977 fuji S-10s. Originally I had set up the drive train to use the 42t inner front chainring, and just left the 52t chainring in place. I started to have chain launching issues, and realized it was because the cog in the rear was more aligned with the outer 52t chainring. To test this, I ran on the outer chainring for a couple weeks and experienced no chain launches, but 52x16t was a bit high.I couldn’t simply swap the front two rings because the 52t front ring wouldn’t fit on the inside track. Thus I simply removed the 52t chainring, and mounted the 42t ring to the outside position. To do this I needed these single bolts because my existing bolts were too wide (to accommodate two chainrings). These worked great and I’ve had no issues so far.Update: I lose a couple of these each season it seems like. Use loctite. Haven’t had any issues with them physically failing, just vibrating loose over the course of the summer. It’s tougher to catch before they fall off since there’s less thread. Seems that I lose them within a day or so once they finally come lose.

Solid
Got these to replace my old chainring bolts on my road bike conversion. The old ones were too big and I had to use spacers/ the spanner nuts were shot and I could barely get the wrench to stay in them. These were a great fit, and plenty of metal on the spanner nut to get good torque. Came fast too

Treat yourself to building and riding a single speed
Very handy/absolutely essential for building a single speed. These work like they should for setting up a single chainring crankset. I have several sets of these in service; wonderful consistent quality.

Good quality
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.

Work great for a SRAM X-Sync ring on FSA Gossamer 110 BCD crank
Used these to mount a SRAM 40T X-Sync (1x) ring to my FSA Gossamer crank (2x) on my CX bike. Works great, look good, and holding secure. I did need to use a flathead screwdriver on the back of the bolts to hold them steady while I applied torque to the bolts. A dual hex setup (6mm/5mm) like I’ve seen on some other bolts would have been nicer.
