anti-seize and torque

[Radfahrer]

On your website you recommend reducing the torque by about 20% when installing bolts that are lubricated with anti-seize paste. After watching two videos about torque wrench myths, I wonder if a 20% reduction is enough.

That's a good video (and a good question). It aligns with my experience and advice:

Yes, depending on the lubricant used, bolt and the piece it threads into material, and even the bolt's diameter and thread pitch, the tightening torque compared to a dry fit can be reduced by 30% or even more. However:

Bicycle parts usually come greased/greasy from the factory, and in most cases the manufacturer's instructions don't specify degreasing them before installation (they simply don't specify whether the torque recommendation is for a dry or a lubricated fit). So, in practice, going about 20% lower works fine.

I've made a torque specs page based on my experience, with anti-seize (mounting paste) used: Bicycle parts tightening torque (N⋅m) specifications.

So, with all that in mind, I think I should edit the article to state just that, in more detail (basically what I wrote in this post). Thanks for the heads up.
Edit:
I've just updated the article.
