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

The Klein Tools 65109IMPCT KNECT 3/8-Inch Drive Deep-Well Impact Socket Set functions as a high-torque mechanical fastening system engineered to drive SAE hex nuts and bolts across electrical, HVAC, and industrial framing installations. 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 kit contains seven 6-point deep-well sockets ranging from 5/16 in. to 3/4 in., a 3-inch 1/4 in. hex to 3/8 in. square impact driver adapter, and a 2-1/2 inch KNECT extension. Precision cold-forged and heat-treated from chromium-molybdenum (Cr-Mo) steel with a corrosion-resistant manganese phosphate coating, this set enables trade contractors to transition impact-rated sockets smoothly between 1/4 in. power impact drivers, 3/8 in. impact wrenches, and KNECT pass-through handles.

Best Used For:

  • High-Torque Utility & Mechanical Fastening: Driving 5/16 in. through 3/4 in. SAE hex bolts, strut channel hardware, and heavy equipment lugs.
  • Extended Thread Clearance: Reaching deep over long protruding threaded rods, studs, and recessed mounting brackets using optimized deep-well socket walls.
  • Impact Driver to Ratchet Adaptation: Utilizing the 3-inch 1/4 in. hex adapter to power 3/8 in. drive impact sockets directly with standard 1/4 in. impact drivers.

Key Performance & Safety Features

  • Cold-Forged Cr-Mo Alloy Steel: Heat-treated chromium-molybdenum impact metallurgy absorbs high rotational torque spikes without wall cracking or socket expansion.
  • Optimized Deep-Well Wall Profile: Slim-profile wall geometry delivers maximum access into restricted spaces and over extended threaded studs.
  • 3-Inch Impact Driver Adapter: Converts 3/8 in. square drive sockets for instant, high-torque operation with 1/4 in. hex impact drivers.
  • KNECT Multi-Purpose System Integration: Extension and adapter components mate directly with KNECT (M) pass-through socket wrenches and manual driver handles.
  • High-Visibility Size Identification: Stamped size callouts with white paint infill and color-coded painted rings ensure fast size selection in low light.
  • MODbox Modular Storage Case: Compact organizer tray nests neatly inside the Klein MODbox system and stacks with matching modular accessory cases.

What's Included

  • (7) 3/8 in. Drive SAE Deep-Well Impact Sockets (5/16 in., 3/8 in., 7/16 in., 1/2 in., 9/16 in., 5/8 in., 3/4 in.)
  • (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 Modular Case

Pro-Tip: When running high-volume unistrut spring nuts or junction box mounting bolts, use the 3-inch impact adapter to drive the 9/16 in. deep-well socket directly from your 1/4 in. cordless impact driver. This setup gives you extended clearance around tight framing members while delivering full impact torque without shearing the adapter drive pin.
