Steel Tri-lobular Screw
Tri-lobular thread rolling screws are used to create strong, uniform load carrying internal threads into untapped materials upon installation. Assembly efficiency and joint performance along with lower in-place fastening cost, are just some of the benefits of using Tri-lobular Screws.
Tri-Lobe screws drive easier than other thread-forming screws, and with uniform torque. They are self-locking and vibration-resistant along the entire length of the thread.
