Introduction to the Structure Subsystem, continued
HINT:
Attach components together
with multiple screws from
different directions to keep
structural members aligned
correctly and for maximum
strength!
When using screws to attach things together, there are three types of nuts which can be used.
• Nylock nuts have a plastic insert in them which will prevent them from unscrewing. These
are harder to install, as you need to use an open-ended wrench to tighten them up. These
nuts will not come off due to vibration or movement.
• KEPS nuts have a ring of “teeth” on one side of them. These teeth will grip the piece
they are being installed on. This means you do not NEED to use an open-ended wrench to
tighten them (but it is still recommended). These nuts are installed with the teeth facing the
structure. These nuts can loosen up over time if not properly tightened; however they will
work great in most applications.
• Regular nuts have no locking feature. These basic hex nuts require a wrench to install and
may loosen up over time, especially when under vibration or movement. They are very thin
and can be used in some locations where it is not practical to use a Nylock or KEPS nut.
WARNING: It is important to be careful when tightening screws. The allen wrenches
may round or “strip out” the socket on the head of the screw if they are not fully
inserted into the socket.
Use care when tightening screws to prevent stripping out the head of the screw!
