Set screws, also known as grub screws, are a type of threaded fastener designed to secure one object within or against another object. Unlike traditional screws that are used to fasten materials together, set screws do not have a traditional head like a Phillips or flat head. Instead, they typically have a hexagonal socket or an allen wrench socket (hex key) on one end, allowing them to be tightened using an appropriate tool.
Set screws are used in various applications:
When using set screws, it's important to ensure proper torque and installation. Over-tightening can damage threads or cause other problems, while insufficient tightening might lead to components becoming loose.
