Description

Unbeatable Fastening Efficiency: 16 Sizes in One Compact Impact-Rated Kit

The Klein Tools 654QS KNECT™ Quad-16 Heavy-Duty Impact Flip Socket Set is the ultimate multi-function solution for professionals looking to maximize their productivity while minimizing tool weight. This revolutionary 6-piece set condenses 16 essential SAE and Metric hex sizes into just four color-coded, deep-well sockets. Featuring a proprietary spring-loaded mechanism, these sockets allow for hands-free size transitions; simply apply pressure to the smaller socket to compress it, instantly exposing the secondary size without stopping your workflow. Whether you are managing extended threads, recessed bolts, or working in confined spaces, these deep-well sockets provide the reach and reliability required for high-torque applications.

Forged from heat-treated, cold-forged steel, this set is built to withstand the rigorous demands of impact drivers and high-torque fastening. The industry-standard color-coded rings allow for rapid size identification at a glance, ensuring you grab the right tool every time. Designed for maximum organization, the Quad-16 sockets can be stored on the included 1/4-inch hex shaft to allow for rapid swapping between eight different hex sizes in seconds. This set comes housed in a MODbox™ compatible accessory case, featuring a dedicated small parts tray for your bits and fasteners, making it a perfectly modular addition to your professional toolkit.

Key Features

  • 16-in-1 Versatility: Combines 16 distinct hex sizes into 4 convenient color-coded impact sockets.
  • Hands-Free Spring Action: Easily access dual hex sizes by applying pressure to the smaller socket to compress it out of the way.
  • Industrial Strength: Heat-treated and cold-forged steel construction designed for long-lasting, high-torque impact driver use.
  • Deep Well Performance: Ideal for managing extended threads and recessed bolts in confined or hard-to-reach spaces.
  • Fast Identification: Painted color rings follow industry standards for quick visual size recognition.
  • Efficient Storage: Keep sockets on the impact shaft to swap between any combination of 8 hex sizes instantly.
  • MODbox™ Integration: Includes an organized accessory case with a small parts tray for modular storage.

What's Included

  • (4) Quad-16 4-in-1 Impact Flip Sockets
  • (1) 1/4-Inch Hex Flip Socket Impact Shaft

Pro-Tip: When working with long-threaded bolts, the deep-well design is your best friend. Ensure the socket is fully seated over the fastener before engaging your impact driver; this prevents rounding of the hex corners and ensures the heat-treated steel can distribute maximum torque effectively.
