Klein Tools 65238 KNECT Essential Deep-Well Heavy-Duty SAE 7-Piece Flip Socket Set

The Klein Tools 65238 KNECT 7-Piece SAE Deep-Well Heavy-Duty Flip Socket Set operates as a coaxial impact-rated driving system engineered to install and remove six standard hex fastener sizes across mechanical and electrical assemblies. Weighing 1-22/100 lbs. and housed in a MODbox-compatible storage case measuring 7 in. L x 3-45/100 in. W x 1-63/100 in. H, this kit contains three color-coded coaxial spring-loaded flip sockets (1/4 x 5/16 in., 3/8 x 7/16 in., and 1/2 x 9/16 in.), a low-profile 72-tooth 1/4 in. square drive ratchet, a 1/4 in. hex flip shaft, and a 3/8 in. square drive nested adapter. Outfitted with dual-drive versatility, this set enables electricians, HVAC technicians, and mechanics to transition deep-well sockets between manual ratchets and power impact drivers.

Best Used For:

  • Electrical & Mechanical Fastener Sizing: Driving 1/4 in. through 9/16 in. SAE hex nuts and bolts using spring-loaded coaxial flip sockets that double output capacity per shaft.
  • Confined Cabinet & Ductwork Ratcheting: Accessing tight clearance hardware with a low-profile 72-tooth 1/4 in. square drive ratchet requiring only 5 degrees of swing arc.
  • Impact Driver to Ratchet Dual-Drive Workflows: Nesting the 1/4 in. hex flip socket shaft into the 3/8 in. square adapter for immediate power tool or manual ratchet attachment.

Key Performance & Safety Features

  • Coaxial Spring-Loaded Flip Sockets: Three color-coded sockets integrate six SAE sizes (1/4, 5/16, 3/8, 7/16, 1/2, and 9/16 in.) to eliminate loose socket clutter.
  • 72-Tooth Low-Profile Ratchet: Compact 1/4 in. square drive ratchet provides smooth gear engagement and high torque leverage inside restricted enclosures.
  • KNECT System Nested Adapters: Dual-drive shaft geometry nests a 1/4 in. hex flip shaft directly inside a 3/8 in. square drive adapter for power or hand driver use.
  • Impact-Rated Steel Metallurgy: Forged heavy-duty steel components withstand high peak rotational torque from power impact drivers without fracturing.
  • Pass-Through Socket Wrench Compatibility: Connects directly with Klein Tools pass-through socket wrenches (Cat. No. 65300) and standard 1/4 in. drive ratchets.
  • MODbox Modular Storage System: Compact clear-lid organizer case locks onto MODbox side rails and stacks with matching modular storage cases.

Pro-Tip: When swapping between 1/4 in. and 5/16 in. fasteners during electrical panel service, push the spring-loaded outer socket sleeve forward to engage the 1/4 in. size, or pull it back to lock onto 5/16 in. hex heads. Stacking two flip sockets onto the extension shaft lets you run all four common HVAC sizes (1/4, 5/16, 3/8, and 7/16 in.) without removing the bit from your impact driver.
