Set Screws & Grub Screws
What are set screws / grub screws and what are they used for?
Set screws are often also referred to as grub screws, and they are used to join metal layers or wood and metal layers together. These are used to join objects together in conjunction with an internally threaded component and no requirement for an additional nut.
Set screws have a hexagon head with a thread that runs the full length of the shank.
