Bi Hexagon Sockets with advanced 12-point side drive design for superior performance and durability. The 12-point profile delivers higher torque than standard sockets, securely gripping worn or damaged nuts and helping prevent rounding of existing fasteners. Each socket features a ball-retaining groove on every face of the square drive, ensuring a secure, positive connection with ratchets, extensions, and other accessories. Designed for efficiency in tight spaces, these sockets require only a one-twelfth turn to engage the next drive point, allowing faster work with minimal handle movement. Ideal for professional mechanics, engineers, and serious DIY users who need reliable, high-performance socket tools.
