Klein Tools 65400KNECT KNECT Essential Pass Through Impact Socket Set SAE Metric 28-Piece

The Klein Tools 65400KNECT 28-Piece Pass Through Impact Socket Set functions as a hollow-core mechanical driving system engineered to run hex nuts down extended threaded rods and recessed studs. Weighing 3-18/100 lbs. and organized in a MODbox-compatible storage case measuring 9-1/4 in. L x 5-1/4 in. W x 1-63/100 in. H, this kit contains a 90-tooth pass-through ratchet requiring a 4-degree swing arc alongside a Cushion-Grip pass-through screwdriver handle. Outfitted with 18 SAE and Metric impact sockets (1/4 in. to 3/4 in. and 8 mm to 17 mm), five chicklet bits, and four adapters, this modular set enables electricians and HVAC contractors to convert components directly for manual ratchet driving, hand screwdriver work, or 1/4 in. impact driver power fastening.

Best Used For:

  • Threaded Rod & Strut Channel Fastening: Running hex nuts continuously down 3/8 in. all-thread rods and unistrut trapeze hangers without bottoming out inside traditional sockets.
  • Confined Cabinet Electrical Assemblies: Operating a low-profile 90-tooth pass-through ratchet requiring only 4 degrees of swing clearance inside tight control panels.
  • Impact Driver & Screwdriver Cross-Conversion: Mounting 1/4 in. hex impact adapters and KNECT adapters to switch components between hand handles and 1/4 in. power impact drivers.

Key Performance & Safety Features

  • 90-Tooth Pass-Through Ratchet: Low-profile ratchet gear provides 4-degree arc swing efficiency to drive nuts on long bolts in restricted clearances.
  • Cushion-Grip Pass-Through Handle: Hollow screwdriver handle accepts KNECT (M) sockets and adapters to permit manual nut driving over protruding threaded rod ends.
  • Dual SAE & Metric Impact Sockets: Covers 18 hex sizes from 1/4 in. through 3/4 in. and 8 mm through 17 mm forged from heavy-duty impact-rated steel.
  • Universal Square Drive Adapter: Converts the pass-through wrench collar to accept standard 1/4 in. or 3/8 in. square drive sockets.
  • Magnetic Bit Holder Integration: Included 1/4 in. magnetic socket doubles as an insert bit holder for driving Phillips, slotted, TORX, and square bits.
  • MODbox System Compatibility: Hardened clear-lid compact case mounts directly onto Klein MODbox rails and stacks with matching modular storage boxes.

Pro-Tip: When installing trapeze hangers on overhead all-thread rods, select the required pass-through socket and attach it to the 90-tooth wrench. Slide the socket directly over the exposed threaded rod end to spin nuts up or down without needing deep-well sockets or open-ended wrenches.
