A trilobular screw, also known as a thread-rolling screw, is a type of screw with a unique design featuring alternating high and low threads. Some of the threads are higher, while others are lower. Trilobular screws are commonly used in applications that require high strength and stability, such as securing machinery and equipment, as well as in construction and bridge structures.

The distinctive feature of trilobular screws is their thread design. The alternating high and low thread shape allows the screw to generate greater friction and resistance during tightening, resulting in a more secure and stable fastening. Additionally, the design of trilobular screws helps prevent self-loosening, enhancing reliability and safety in various applications.
