Thread locker under the bolt head?
Thread locker under the bolt head?
(OP)
Does anyone apply threadlocker under the head of the bolt?
Frequently, bolts are preloaded by measuring the torque used to tighten the bolt. Lubricants are frequently used on bolts to reduce the variability of the friction. When lubricating with oil, some people will recommend putting oil under the head of the bolt (assuming that the bolt is being rotated instead of the nut). Threadlockers reduce the friction (during installation) and reduce the variability of the friction - just like oil. Putting threadlocker under the bolt head would help just like oil under the head, but putting thread locker under the head feels weird to me. Is it common to put threadlocker under the bolt head?

I've read in textbooks that threadlockers can act as lubricants, but some of the threadlocker datasheets made it sound like they would increase rather than decrease the friction (like you said). I was not sure if I was reading things correctly or not. Thank you for the insight.

IF (big "IF" there) you are always working in a perfect continuously operating assembly line with no breaks, it "might" work. But room air changes and startup and shutdown times will kill the first and last items assembled.
Also, forget about in-field repairs being done consistently to original spec's.
Use a lubricant.
