Smart Fasteners do not automatically add nuts or washers to fasteners. You add
them in the Smart Fasteners PropertyManager. Each
Group of fasteners has an associated
Top Stack (washers added under the head of the
fastener) and Bottom Stack (washers and nuts added
to the end of the fastener).
See Toolbox Help: Toolbox - Smart Fasteners to select or
clear these options:
- Change fastener length to ensure
minimum thread engagement.
- Change stack components when fastener
size is changed.
