Screws that are used in the digital sender
This table describes the screws that are used in the digital sender and provides guidelines to help
determine where each type of screw is used. The screws can vary in length depending on the thickness
of the material that is being fastened. Always note where each type of screw is located and replace each
one in its original location.
NOTE: When you are disassembling the product, place the screws into the chassis holes from
which they were removed. This prevents their loss, and ensures that the proper type and length
of screw for each location is used when the product is reassembled
Table 5-1 Common fasteners that are used in this digital sender
Drawing and description Purpose
Phillips-head machine screw with captive
star washer
This screw is used to fasten metal to metal when good electrical contact is needed.
This screw also provides high resistance to loosening.
Phillips-head screw with self-tapping
threads
This screw is used to fasten sheet metal or plastic to plastic frames. The deep,
coarsely spaced threads provide an increased holding capability while decreasing
the possibility of stripping the target hole.
NOTE: To install a self-tapping screw, first turn it counterclockwise to
align it with the existing thread pattern, and then carefully turn it clockwise
to tighten it. You will feel resistance and hear the screw click when it
engages the existing threads in the hole. Do not overtighten the screw. If
a self-tapping screw-hole becomes stripped, repair the screw-hole or
replace the affected assembly.
Phillips washer-head machine screw with
a broad, flat washer attached to the screw
head
This screw is used to fasten sheet metal parts to the sheet metal chassis. It spans
large clearance holes and distributes the load by increasing the bearing surface.
