Europa-List: Re: fastening duct to firewall/footwell

[jonathanmilbank <jdmilbank@yahoo.co.uk>]

You have a good point, which is why I didn't use bolts but rather screws of the
type which hold my spinner to its backing plate. They're threaded all the way
up to the head and tightening with a screwdriver minimises the possibility of
over-torqueing. After all, they really are needed only to tolerate loads in 
shear
and shouldn't be tensioned out by the duct sidewalls.
