Mark, I currently use the ones provided
by Tracy for the Redrive. I intend to replace them with the metal type,
but need to order that size. Also, I want to check with Tracy and make
certain there is no reason (that I have not considered ) against using
them.
Again, I admit that its probably
overkill and unnecessary. On the other hand, I see no reason
not to use metal locknuts as appears to be a common practice for
FWF.

limits on Locknuts
Ed,
I recently became aware of the practice of
using only metal locknuts on everything fwf. So, I ordered a couple
dozen of each size and replaced everything fwf on my installation except for
the ones used on the psru bolts. Did you change those to metal or use
the nylon supplied with the redrive?

is what I found with a quick search for locknuts with plastic/nylon
inserts. The max temperature range is listed as 250F. The metal
ones go up to 1000F. So perhaps metal is overkill - but 250F does not
provide me with a comfort margin I would like under the cowl.
I agree that the prop
bolt nuts should never see 250F, but, the question is what effect elevated
temperatures short of 250F do to the life of the material.
So it would
appear that what ever makes you feel comfortable would be the way to
go. Me, for the prop and most things forward of the firewall, I'll
continue to use the Metal Lock nuts.
