Klein Tools 65400KNECT Pass-Through Impact Socket Set: Unboxing & First Impressions
Finding a socket set versatile enough to handle field repairs without consuming valuable storage space is a constant challenge for truck maintenance and mechanical work. In this unboxing and first-look overview, Jim Kinkade explores the Klein Tools 65400KNECT Pass-Through Impact Socket Set, evaluating its modular pass-through architecture, impact readiness, socket and bit assortment, and integration into the Klein MODbox system.
The Pass-Through Advantage: Tackling Infinite Threaded Rods
The defining feature of the KNECT system is its hollow, pass-through architecture:
- Open-Socket & Wrench Design: Standard deep-well sockets bottom out when running nuts onto long bolts or extended threaded rods. The KNECT sockets and matching ratchet feature a completely hollow center, allowing threaded rod or extended stud threads to pass straight through the head without obstruction.
- Fine-Tooth 90-Tooth Ratchet: Engineered for tight-clearance mechanical compartments, the low-profile ratchet features 90 teeth, delivering a tight 4-degree swing arc for rapid fastening in confined quarters.
- Hollow Cushion-Grip Nut Driver: The set includes Klein’s classic ergonomic cushion-grip handle, redesigned with a hollow core so you can hand-drive pass-through sockets over protruding bolts. The sockets lock in securely via a splined retaining ring.
- Pass-Through Extension: When extra reach is needed, the included pass-through extension tube attaches between the handle/ratchet and the socket while maintaining the open center channel.
Impact Rated: Triple-Duty Versatility
Rather than confining users to hand tools, the entire KNECT set is built for powered use:
- 1/4″ Hex Impact Adapter: The kit comes equipped with a quick-release 1/4″ hex collet adapter, allowing all sockets and extensions to run directly on an impact driver.
- Triple-Duty Flexibility: Mechanics can seamlessly move the same socket between the 90-tooth hand ratchet, the cushion-grip manual nut driver, and a 12V/18V impact driver.
Complete SAE, Metric & Driver Bit Assortment
The 65400KNECT kit covers the essential fastener sizes needed for automotive, heavy equipment, and electrical work:
- SAE Sockets: 5/16″, 3/8″, 7/16″, 1/2″, 9/16″, 5/8″, 11/16″, and 3/4″.
- Metric Sockets: 8mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, and 17mm.
- 1/4″ Bit Adapter Socket: Converts the pass-through driver/ratchet to drive standard 1/4″ hex screwdriver bits.
- Included Screwdriver Bits: T20 Torx, #2 Square (Robertson), 5/16″ Slotted/Flathead, #1 Phillips, and #2 Phillips.
- Extended Bit Driver: An elongated bit holder that integrates with the socket set and shares cross-compatibility with other Klein precision driver kits.
Rugged Case Design & MODbox Stacking
- Interlocking MODbox Compatibility: The heavy-duty polymer case features secure slide-latch closures and top/bottom connection clips that snap directly onto other Klein MODbox cases (such as the precision bit driver set), creating a secure, modular stack.
- Built-In Measuring Ruler: The underside of the case features an embossed inch/metric ruler for quick on-the-spot sizing and wire cuts.
- Truck & Field Organization: Compact enough to slide beneath a truck seat or tuck into an everyday carry tool bag, this set allows drivers and technicians to consolidate their mobile tool loadout without sacrificing functionality.
The Verdict
The Klein Tools 65400KNECT Essential Pass-Through Impact Socket Set eliminates the clearance limitations of standard sockets while providing full impact-driver adaptability. For technicians working out of a rig or seeking an all-in-one mobile mechanical set, it delivers professional-grade modularity in an ultra-portable footprint.
Conclusion
Stay tuned for my updated review. Since this unboxing, I’ve used this Klein Tools set a lot! You can find this set on Amazon, as well as Lowe’s Home Improvement.
One thing I forgot to mention in this video is that the set comes with a standard 3/8″ adapter for regular sockets.
