The Star Slot can transmit greater torque than a Phillips or slotted slot, and the tool is less prone to slipping, effectively preventing thread slippage issues and enhancing installation efficiency and connection reliability. The hemispherical head provides a larger contact area, dispersing local stress. The integrated washer beneath the round head significantly increases the contact area with the connected component, thereby reducing unit pressure, preventing the surface of soft materials (such as plastic, wood, thin metal plates) from being crushed or dented. It can increase the stress-bearing area, prevent loosening, and protect the surface of the connected component. Th…
