Another Illustration

Here you can see how the countersunk hole on the right has forced & compressed the butyl against the bolt and into the threads creating a great seal. The bolt on the left was not countersunk and has very little sealing surface area around the bolts shank or threads.

Thank you for getting this posted on line again. I was looking for this a couple of weeks ago, and was glad to come back and find all the text posted. In the interum I couldn't find any other source of a clearly illustrated process to rebed hardware.
Thank You!
