Klein Tools quietly added two ratcheting socket wrench sets to its KNECT line, and both are now on Amazon. The 17-in-1 set, model 65431LP, lists at $95.99. The smaller 9-in-1, model 65430LP, is $69.98.
Neither set is a power tool. They are worth a look anyway because of how they are built: low-profile impact sockets that pass all the way through the ratchet head, so you can run a nut onto a stud that would normally bottom out a standard socket.
What You Get
The 65431LP carries 16 sockets, 8 SAE and 8 metric, on a 3/8 in. drive. The 65430LP carries 8 SAE sockets only. Both use the same flex-head pass-through ratchet, which locks in at least 11 positions so you can angle the handle into a spot where a straight ratchet will not fit.
| Model | Pieces | Sizes | Price |
|---|---|---|---|
| 65431LP | 17 (16 sockets + ratchet) | SAE 1/4 to 9/16 in., metric 7 to 14 mm | $95.99 |
| 65430LP | 9 (8 sockets + ratchet) | SAE 1/4 to 9/16 in. | $69.98 |
Sockets are cold-forged Cr-Mo steel with a manganese phosphate finish, and Klein rates them for impact use.
Each socket has a color-coded band plus a laser-etched size. That sounds like a small thing until you are upside down under a dash trying to read a stamp.
Both sets ship in a MODbox accessory case that connects to Klein’s other modular boxes, and both work with the KNECT (M) adapter range if you want to run them off a driver.
Why the Pass-Through Matters
A standard socket has a fixed depth. If the fastener sits on a long threaded rod, the socket bottoms out before it reaches the nut. A pass-through socket has an open center, so the stud goes right through the head and out the back of the ratchet.
That is the same idea Klein put into its 2-in-1 adjustable wrench with a pass-through ratchet, which we covered when it landed. The new sets push it into a full socket lineup with a flex head, which is a more useful tool for suspension work, strut mounts, and anything where a stud is longer than a socket.
The trade-off is real. Low-profile sockets have less material around the fastener, and a pass-through head is bulkier than a plain ratchet head. Klein claims impact rating on these, so the steel should hold up, but a $95 set of sockets is competing with established mechanic sets that carry far more pieces for the same money.
Who Should Buy
If you already own a decent socket set and keep running into studs that are too long, the 65431LP fills a specific hole. Buy the 17-piece. The 9-in-1 skips metric entirely, which is a hard sell in 2026 for anything touching a modern vehicle.
If you are building a toolbox from zero, put the money toward a broad mechanic set first. A pass-through set is a specialist addition, not a foundation.
