Preventing oxidation on screws

sam218 said:

Is it better to put grease or oil on bolts such as seatpost, chainring, and stem bolts to prevent rust?

Grease on threaded stuff.

Suggest using an anti-seize compound on threaded parts, seat post and crank faying surfaces to stop any corrosion and heartache when it comes to removing the components in future.

Grease does the same thing.

Anti-seize compounds are typically a mixture of finely ground materials, such as nickel, graphite, lead, copper, aluminum, zinc, and molysulfide, mixed with mineral oils. These compounds provide a good insulating layer between metals, preventing galling in the threads. These compounds provide much longer protection in adverse and wet conditions as compared to grease. The various grades and types of compounds will vary with their ability to perform at high temperatures, heavy loads, chemical exposure, and stress. However, the stress and loads experienced on the bicycle are less than the automotive uses these compounds are designed for. Use care when applying these compounds and follow the safety directions of the manufacturers.

Yeah, I know the theory,and in a lifetime of actual use have never had an issue with using grease.Use whatever spins your beanie,but the bigger issue comes from using nothing.

Grease everything.
