Klein KNECT 65500KNECT 39-Piece Impact Pass-Through & Flip Socket Set

The Klein KNECT 65500KNECT 39-Piece Impact Pass-Through & Flip Socket Set is a modular fastener driving system engineered to run hex nuts down extended threaded rods, long studs, and recessed bolts. Forged from chrome-moly and chrome-vanadium impact-rated steel, this 5.47-pound collection features a 90-tooth pass-through ratcheting wrench operating with a tight 4-degree arc swing. Housed in a MODbox-compatible clear-lid case, this 39-piece kit includes 18 pass-through sockets, 6 heavy-duty flip sockets, a cushion-grip handle, and KNECT adapters to solve deep nut-running, high-torque impact driving, and workspace clearance challenges across electrical, HVAC, and mechanical trades.

Best Used For:

  • Electrical & HVAC Overhead Trapeze Mounting: Running hex nuts up long 3/8-inch and 1/2-inch threaded drop rods on unistrut trapeze hangers without socket bottoming.
  • High-Torque Impact Driver Fastening: Driving hex head lag screws, anchor bolts, and structural fasteners using 1/4-inch hex impact driver adapters.
  • Tight Space Mechanical Assembly: Fastening nuts in confined junction boxes and equipment housings using the 90-tooth 4-degree arc swing ratcheting wrench.

Key Performance & Safety Features

  • Hollow Pass-Through Design: Hollow socket and ratchet head architecture allows unlimited bolt or threaded rod protrusion through the center of the tool.
  • 90-Tooth Low-Arc Ratcheting Wrench: Requires only a 4-degree arc swing for fluid fastener manipulation in restricted or cramped work zones.
  • Heavy-Duty Impact-Rated Steel: Chrome-moly and chrome-vanadium alloy construction absorbs continuous impact driver shock loads without cracking.
  • Dual-Ended Heavy-Duty Flip Sockets: Reversible socket design combines dual SAE and Metric drive sizes into single socket bodies to reduce kit bulk.
  • Universal KNECT System Adapters: Connects pass-through sockets directly to 1/4-inch, 3/8-inch, and 1/2-inch square drive ratchets or impact drivers.
  • MODbox Stackable Modular Storage Case: Clear-lid protective carrying case latches seamlessly onto Klein MODbox storage stacks and toolboxes.
