What Are Knurled Pins?<\/strong><\/h2>\n

Knurled pins are specialized fasteners featuring a textured (knurled) surface designed to enhance grip, prevent rotation, and improve retention when pressed into a mating hole. The knurling\u2014typically a diamond, straight, or crosshatch pattern\u2014creates friction and mechanical interference, ensuring a secure fit without requiring adhesives or additional locking mechanisms. These pins are commonly used in assemblies where vibration resistance and anti-slip properties are critical1<\/span>3<\/span>.<\/p>\n
