KK Construction
Ko-Ken Construction Tools are specialized hand tools engineered specifically for construction applications where standard sockets, wrenches, and ratchets fail to provide adequate access, torque, or durability. These tools address unique fastener types and challenging installation conditions common in:
-
Concrete formwork (form ties, wing bolts, anchor screws)
-
Steel erection (spud bolts, structural connections)
-
Scaffolding assembly (frame connections, couplers)
-
Heavy construction (bridge work, high-rise buildings, industrial facilities)
