The 567 threadlock was applied last night to the bolt flange and threads. The bolt was installed and tightened down. It was removed this morning and more effort was needed to do this than to install it. The 567 locks the threads sorta not a much as blue threadlocker but more than none at all. That is what I want.
The threads were wiped clean, more 567 was spread on the threads and flange, and a stripping test was done. The test was stopped before anything yielded. The potential clamping force this bolt can provide is far more than what I need.
The insert provides more external thread area in the aluminum wheel to resist shear as well as a longer engagement length. Maximum preload force for internal thread shear was 2,240 pounds using the 0.64 safety factor. Now it is 5,240 pounds in the wheel using the same factor.
Internal shear in the insert along the titanium bolt is increased, too. This is 'cause the yield strength of the steel insert is much more than the aluminum. Max preload was 2,240 pounds and it is now 4,610 pounds.
A persuasive argument is made for using a 0.5 multiplier, instead of 0.64, in the article with the Hooke's Law formula previously posted. The maximum recommended preload for the bolt in tensile load changes to (0.5 / 0.64) x 4,640 = 3,620 pounds using this formula. That is the force that will be used for this bolt. Stretch is 3.62 x 0.000835 = 0.0030 inches at this load. That is well within the capacity of this connection and it equals between 15 and 16 lbs-ft torque.
