What Are The Buttress Threads Of Fasteners?

Buttress threads are a type of thread profile found on fasteners and in threaded connections that are designed for applications where there is a predominant force acting in one direction. These threads are characterized by a triangular shape with one side that is almost perpendicular to the thread axis (forming the load-bearing face), and the other side sloped, typically at a 45-degree angle. This design allows the threads to handle high axial forces in one direction while being easier to disengage or unscrew than other thread profiles when the force is applied in the opposite direction.

As a professional fastener supplier, Xinchi fastener company is glad to introduce some advantages of buttress thread’s design.

High Strength and Load Capacity: The almost vertical face on one side of the thread bears the load efficiently, providing high strength and resistance to the applied force. This makes buttress threads suitable for applications with high axial loads.

Efficiency in Transmission: Because the load-bearing face is nearly perpendicular to the direction of the force, buttress threads can efficiently transfer force with minimal energy loss. This makes them ideal for applications where the force is primarily in one direction, such as in vises, presses, or even in the plastic bottle cap industry.

Ease of Manufacture: Compared to some other specialized thread profiles, buttress threads can be relatively easy to manufacture, allowing for cost-effective production.

Less Wear: The design can result in less wear on the threads when they are subjected to repeated forces in the primary direction of load, extending the lifespan of the threaded connection.
