setscrew
Quick Summary
A setscrew is a type of screw used to prevent relative movement between two parts. It is screwed tightly into one part, pressing against another to hold them in place. Setscrews can have various types of points, such as cup-shaped, conical, or cylindrical, and may feature slotted or square heads. They are also used to regulate valve openings or spring tension. A setscrew wrench, also known as an Allen wrench, is used to tighten them.123
