Ko-Ken Socket Sets, Impact Sockets & Ratchet Wrenches
Ko-Ken is a Japanese precision tool manufacturer established in 1946, producing socket sets, ratchet handles, torque wrenches and speciality hand tools to JIS and ISO standards. Ko-Ken's manufacturing is built on close-tolerance machining from chrome molybdenum and chrome vanadium steel, with a reputation among mechanics and maintenance technicians for consistent socket fit, low ratchet drag and long service life under heavy-duty use. AIMS Industrial stocks Ko-Ken socket sets and ratchet tools for workshops, mine site maintenance and industrial facilities requiring quality Japanese hand tools.
Ko-Ken Socket Sets & Ratchet Wrenches
Ko-Ken socket sets cover all three primary drive sizes -- 1/4", 3/8" and 1/2" drive -- in both metric and AF, with matching ratchet handles built to the same dimensional tolerances.
- Ko-Ken 1/4" Drive Socket Set: Compact metric socket set for tight-access fastener work on instrumentation, small engine components and electrical panel connections; includes ratchet handle, extension bars and hex sockets

- Ko-Ken Ratchet Handle: Fine-tooth ratchet with reversible mechanism and ergonomic knurled grip; chrome vanadium construction with sealed head for resistance to oil contamination in workshop environments
Ko-Ken Impact Sockets & Deep Socket Sets
Ko-Ken impact sockets are hardened to resist the shock loading of air and electric impact wrenches -- essential for fastener removal without cracking that occurs when chrome sockets are used on impact tools.
- Ko-Ken Impact Socket Set: Black phosphate-finish impact sockets in 1/2" and 3/4" drive; chrome molybdenum steel with thicker walls than standard chrome sockets to withstand repeated impact cycling on heavy plant
- Ko-Ken Deep Socket Set: Extended reach metric sockets for fasteners with protruding studs, wheel nuts and long-thread applications; available in 1/4", 3/8" and 1/2" drive configurations
- Ko-Ken Hex Bit Socket Set: Combination bit socket set including hex, Torx and Phillips bits on 1/4" and 3/8" adapters; useful for machinery panels, access covers and mechanical assemblies using recessed fasteners
