The definition of fasteners as stated from Wikipedia is:
a hardware device that mechanically joins or affixes two or more objects together.
Is the definition of mechanical here sense 10 from Dictionary.com? I was confused because I figured the use of fasteners doesn't necessarily require machinery so if it's not the definitions related to machinery then it must mean the physical forces that you apply to the fastener when used to join things together?
