Square Head Set Screws, Cup Point, 18-8 Stainless

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.

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.
