Screwhorn

Screwhorn refers to a type of mechanical fastener designed with a helical thread that is intended to be driven into a material by rotation. Unlike traditional screws, screwhorns are often characterized by a coarser or more aggressive thread pitch, sometimes with a self-tapping feature. This design allows them to create their own threads in softer materials such as wood, plastic, or certain metals, eliminating the need for a pre-drilled pilot hole in some applications. The term "screwhorn" is not a standardized industry designation but is more commonly used colloquially or in specific trade contexts to describe fasteners with these particular thread characteristics. The specific geometry of a screwhorn can vary, but the defining feature is its ability to efficiently penetrate and secure into a substrate through rotational force and its distinct thread pattern. They are often employed in situations where rapid assembly or the fastening of materials without prior hole preparation is desired.
