Klein Tools 65109IMPCTM KNECT 3/8-Inch Drive Metric 9-Piece Deep-Well Impact Socket Set

The Klein Tools 65109IMPCTM KNECT 3/8-Inch Drive Metric Deep-Well Impact Socket Set functions as a high-torque mechanical fastening kit engineered to torque metric hex fasteners across commercial machinery and electrical assemblies. Housed in a MODbox-compatible storage case measuring 9-1/4 in. L x 3-45/100 in. W x 1-63/100 in. H and weighing 2.4 lbs., this 9-piece system features seven 6-point deep-well sockets ranging from 10 mm to 21 mm, a 3-inch 1/4 in. hex to 3/8 in. square drive impact adapter, and a 2-1/2 inch KNECT extension shaft. Forged from cold-forged, heat-treated chromium-molybdenum (Cr-Mo) steel with a black manganese phosphate finish, this kit allows trade technicians and industrial mechanics to switch deep-cavity sockets between 1/4 in. power impact drivers, 3/8 in. impact wrenches, and KNECT pass-through handles.

Best Used For:

  • High-Torque Metric Fastener Maintenance: Driving 10 mm through 21 mm metric hex bolts, motor frame mounts, and industrial panel lugs.
  • Deep-Cavity Stud & Thread Clearance: Reaching deep over extended metric studs, long protruding threaded rods, and recessed mounting brackets using optimized socket walls.
  • Impact Driver Cross-Conversion: Utilizing the 3-inch 1/4 in. hex adapter to run 3/8 in. square drive sockets directly on cordless 1/4 in. impact drivers.

Key Performance & Safety Features

  • Cold-Forged Cr-Mo Alloy Metallurgy: Heat-treated chromium-molybdenum impact steel absorbs heavy rotational torque spikes without wall spreading or cracking.
  • Optimized Thin-Wall Geometry: Deep-well socket walls provide extended axial clearance over protruding studs while fitting into restricted component recesses.
  • 3-Inch Quick-Connect Driver Adapter: Converts 3/8 in. drive impact sockets for instant operation with standard 1/4 in. hex impact drivers.
  • KNECT Pass-Through Compatibility: Multi-purpose adapter and extension connect directly with KNECT (M) pass-through ratchets and screwdriver handles.
  • High-Visibility Size Identification: Stamped size numbers with white paint infill and color-coded bands allow immediate socket selection in dimly lit work areas.
  • MODbox Modular Storage Case: Compact organizer tray rests inside the Klein MODbox ecosystem and stacks securely with matching modular accessory cases.

What's Included

  • (7) 3/8 in. Drive Metric Deep-Well Impact Sockets (10, 13, 14, 15, 17, 19, and 21 mm)
  • (1) 3 in. Long 1/4 in. Hex to 3/8 in. Square Drive Impact Adapter
  • (1) 2-1/2 in. KNECT™ Extension
  • (1) MODbox™ Compatible Compact Storage Case

Pro-Tip: When servicing metric machinery bolts or electrical enclosure grounds, connect the 3-inch impact adapter directly into your 1/4 in. impact driver. The Cr-Mo steel construction handles continuous impact cycles without cracking, letting you run deep-well metric sockets up to 21 mm on cordless power drivers without swapping tools.
