With the introduction of “Duratec”, selfthreading screws have been used to mount many of the
parts and assemblies to the structure. If is important that when replacing these screws, they be
threaded into the original screw threads. The proper procedure for doing this is to insert the
screw into the hole and turn the screw conterclockwise until the screw can be felt to “drop” in
place. An audible “click” may also be herad. Once the screw is properly in place, it may then be
tightened.
