KK Construction

Ko-Ken Construction Tools are precision-engineered hand tools designed for demanding construction environments where conventional sockets, wrenches, and ratchets can’t deliver the necessary access, torque, or durability. Built to tackle unique fastener types and tough installation challenges, these tools excel in applications such as:
  • Concrete formwork (form ties, wing bolts, anchor screws)
  • Steel erection (spud bolts, structural connections)
  • Scaffolding assembly (frame connections, couplers)
  • Heavy construction projects (bridges, high-rise buildings, industrial facilities)
