Six Lobe SEMS Screw, also known as a Torx SEMS Screw, is a high-performance fastening solution designed for efficiency, precision, and reliability. It combines a six-lobe (Torx) drive system with a pre-attached (captive) washer, delivering excellent torque transmission and eliminating the need for separate washer assembly.

The six-lobe drive minimizes cam-out (slipping), allowing higher torque application with reduced wear on tools and fasteners. This makes it especially suitable for automated assembly lines and applications requiring consistent tightening. The pan head (or as specified) provides a wide bearing surface, while the integrated washer ensures even load distribution, surface protection, and resistance to loosening caused by vibration.

Manufactured from high-quality materials such as Mild Steel, Stainless Steel (SS 202 / SS 304), and high tensile grades, Six Lobe SEMS Screws offer superior strength, durability, and corrosion resistance, making them ideal for demanding environments.

These screws are widely used in automotive, electronics, appliances, precision equipment, and industrial assemblies where high torque, accuracy, and efficiency are essential.
