Klein just rolled out a wrench that does two jobs in one hand. The new 5076RT is a 6-inch wide-jaw adjustable wrench with a pass-thru ratchet built into the end. It is a clever mashup in a tool category that rarely sees anything genuinely new. Klein lists it at $25, and a 10-piece kit version ships for $60.
What you are actually buying
| Product | Price | What’s included |
|---|---|---|
| Klein 5076RT | $25 | Adjustable wrench with pass-thru ratchet, 3/8″ square drive adapter |
| Klein 5076RTK | $60 | 10-piece Knect set with short sockets, extension, adapters, carry case |
Both are available on Amazon right now. The standalone wrench includes a 3/8-inch square drive adapter, so you can run it with sockets you already own. The kit version adds a short socket set plus a compact case, and it plugs into Klein’s broader Knect ecosystem.
The catch worth knowing
There is a real limitation here. With a pass-thru layout you can grab either the bolt head or the nut, but not both at once. That is fine for plenty of jobs, but if you need to hold the bolt head and turn the nut simultaneously, a standard adjustable wrench or a socket on the head is still the move. The pass-thru design is really about speed on single-side fasteners and working in tight spots where a socket would otherwise slip over a long stud.
The other thing to watch is compatibility. Pass-thru socket interfaces are often proprietary across brands. ToolGuyd notes that Gearwrench, Craftsman, Kobalt, and Husky come from the same parent company and tend to be cross-compatible, but Klein’s Knect interface is still an open question. You will not know for sure until you try.
Where it fits
Klein is leaning hard into the Knect modular ecosystem rather than selling this as a one-off. A single tool that is both a wrench and a ratchet is a niche play, but the whole point is that it slots into a wider interchangeable system. It competes more with the modular hand tool kits cropping up than with a heavy-duty contractor wrench.
For comparison, Milwaukee has been pushing into the wrench space too, with parallel-jaw pliers wrenches and click torque wrenches. Those are heavier-duty picks with higher price tags. If you want a cheap, light-duty option for fast plumbing and electrical fastener work, the Klein is a bargain. If you need real torque control or a better reach, look at the options below.
How to shop it
Both Klein wrenches are live on Amazon. Prices are current as of this announcement and can shift. The branded versions we tested and ranked are worth a look if you are building out a garage or shop kit.
Who this wrench is for
This is a light and mid-duty tool, not a heavy contractor winner. It shines in electrical, plumbing, and HVAC fastener work where you are reaching into panels or tight spots and need to spin a nut fast. The pass-thru end means you can thread the ratchet over a long stud or bolt where a closed socket would bottom out.
It is not the tool for stubborn, corroded bolts. For those you want a breaker bar or a heavy-duty ratchet with real leverage. At 6 inches, the Klein is compact, and that is the trade-off. You get reach and speed on accessible fasteners, not brute torque.
Frequently asked questions
Does the pass-thru end work with standard sockets? It comes with a 3/8-inch square drive adapter, so yes, you can use sockets you already own. The Knect-specific sockets are optional.
Is the kit worth $35 more? The 5076RTK adds a socket set, extension, adapters, and a carry case. If you do not already own small short sockets, the kit is the better value. If you have a drawer full of them, save the money and buy the standalone wrench.
Is this Klein Knect system compatible with Gearwrench or Craftsman? Pass-thru interfaces are often proprietary, and cross-compatibility is not confirmed yet. Brands from the same parent group tend to share, but Klein’s Knect is still unproven against them. You will not know for sure until you test it.
