Types of screws
WARNING! Make sure that components are replaced with the correct screw type. Using the
incorrect screw (for example, substituting a long screw for the correct shorter screw) can cause damage
to the product or interfere with product operation. Do not intermix screws that are removed from one
component with the screws that are removed from another component.
For a complete list of screw types and part numbers, see the Parts chapter.
