The 6-lob low-head cap has a lower head (up to about 65%) than a typical 6-lob cap, and it takes up less space after tightening and is lighter, making it ideal for making equipment even more compact and lightweight. This is a valid screw.
The 6-lob cap is a TORX® standard screw developed by Kamkar Corporation (currently Acument Corporation) in the United States, and is variously called Hexalobular (6 lobules), Hex Lobe (6 protrusions, earlobes), Hex Lobe, etc.・It's a bolt. It is used in various fields around the world, including the aircraft and automobile industries, electronic and electrical products, and various industrial machinery.
A major feature of the 6 lob is that the recess is composed of an arcuate curve. Due to the smooth fit and tightening drive angle of approximately 75° to the contact surface, torque transmission efficiency is higher than conventional cross recesses and hexagonal recesses, and cam-out does not occur. In addition, there is less concentration of stress that can cause wear and tear, and there is no deformation of the bolt, making it suitable for speeding up work and automation. Also, because of the specially shaped recess, it can also be expected to have a ``tamper-proof'' effect.
