MM 12-point sockets (D6K)

MM D6K 12‑point sockets (also called bi‑hex or double‑hex sockets) are designed to engage 12‑point fasteners and are commonly used in automotive, industrial maintenance, and assembly applications where quick alignment and efficient turning are helpful (application dependent; verify per listing). Compared with 6‑point sockets, 12‑point designs can offer more engagement positions, which can make it easier to seat the socket in tighter spaces or when you have limited swing arc (application dependent). Selecting the right 12‑point socket comes down to matching the drive size and socket dimensions to your fastener and torque requirements (per listing).
