Smart Fasteners – automatic machine for assembling the structure
By default, SOLIDWORKS has created associations and the program knows itself, what fastener to insert into what hole (counterbore, conical, plain hole etc.). You can also edit components while inserting, but you can change the default bindings.
If you want to change the fastener assignment to a given hole type from hole wizard – you have to open Toolbox Settings and turn on the tab 1. You can check there, what is assigned by default.
Wanting to change the association, press the button Reassign and select the appropriate type of fastener.
