Seem to do what they're supposed to
These bolts are a little shorter than those from the original chainring, so can tighten securely without spinning when swapping to a TA chainring.
They seem well machined, but a little on the pricey side for five bolts.

The dogs bolts.
If you need bolts to do the job these will do just fine!

Does the job but fidley to fit & tighten
At the end of the day these have done the job expected but the back side of the bolt with the horizontal groove doesn't hold tools well so found it difficult to tighten the bolts.
The chain ring bolts with the hex front and torx back have a much better grip on tools are way easier to tighten.
No a biggie, just a bit of a fiddle. It does stop my tenancy to over tighten, perhaps?

What are the lengths of the threads/sleeves on the bolts?
I have two front chain rings but they are not connected with the same bolts and may therefore, be smaller single ring bolts. The thread of the male bolt is about 6mm whilst the sleeve is about 4mm (lip not included on either measurements). Would these be suitable? Thanks
I have a damaged Shimano 6750G (50t) 110pcd outer ring that I need to replace. Looking at the Wiggle Shimano chain ring section, from the images available Wiggle would not appear to sell a replacement ring (specific Shimano part number required is Y1LL98020). This outer ring is a little unusual in that it has the threads for the 5 x chain ring bolts embedded in it. What I am wondering is if I purchase the Shimano FC-R600 outer ring (https://www.wiggle.co.uk/shimano-110-pcd-fcr600-10-speed-outer-chainring/) and these bolts do they include the thread attachment that the bolt would screw into as well?
Am I correct in assuming the bolts are long enough for a double (50-34T) chain ring combination or are they designed for single/triple?
