Klein Tools 65239 KNECT Flip-20 SAE Metric 13-Piece Impact Socket Set

The Klein Tools 65239 KNECT Flip-20 13-Piece Impact Socket Set functions as a dual-drive coaxial socket system engineered to install and remove 20 SAE and Metric hex fastener sizes. Weighing 2-69/100 lbs. and housed 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 10 color-coded coaxial spring-loaded flip sockets, an extended flip shaft, a 1/4 in. hex adapter, and a 3/8 in. square drive nested adapter. Outfitted with high-torque impact metallurgy, this set enables electricians, HVAC technicians, and mechanics to transition deep-well sockets between 3/8 in. square drive ratchets, KNECT pass-through wrenches, and 1/4 in. power impact drivers.

Best Used For:

  • Dual SAE & Metric Fastener Driving: Servicing 1/4 in. through 13/16 in. and 8 mm through 18 mm hex nuts using 10 space-saving 2-in-1 flip sockets.
  • Impact Driver to Ratchet Dual-Drive Workflows: Nesting the 1/4 in. hex flip shaft into the 3/8 in. square adapter for seamless shifting between power impact tools and hand ratchets.
  • Commercial Mechanical & Panel Assembly: Fastening electrical box lugs, unistrut hardware, and HVAC cabinet bolts without carrying bulky individual socket sets.

Key Performance & Safety Features

  • 10 Coaxial Spring-Loaded Flip Sockets: Combines 20 total sizes (5 SAE and 5 Metric socket pairs) into 10 color-coded bodies to cut tool bag weight and storage volume in half.
  • Dual-Drive Nested Adapter Design: 1/4 in. hex flip socket shaft nests inside a 3/8 in. square drive adapter for direct connection to ratchets or power drivers.
  • Stackable Socket Shaft Geometry: Six smaller socket sizes (1/4 to 9/16 in. / 8 to 14 mm) stack on the extension shaft for rapid size changing during repeated installations.
  • Impact-Rated Steel Metallurgy: Precision-forged steel alloy withstands intense rotational impact forces and high peak torque without spreading or cracking.
  • Pass-Through Wrench Integration: Specialized 3/8 in. square adapter mates with Klein pass-through socket wrenches (Cat. No. 65400) and standard 3/8 in. ratchets.
  • MODbox Storage Case with Small Parts Tray: Clear-lid organizer mounts to MODbox rails and features an internal tray for loose fasteners, washers, and bits.

Pro-Tip: To quickly switch between metric equipment bolts and standard SAE framing hardware, push forward or pull back on the spring-loaded outer sleeve of the required socket body. For maximum field efficiency, leave your two most-used flip sockets pre-stacked on the extended 1/4 in. hex shaft inside your impact driver chuck to instantly cover four hex head sizes on the fly.
