Klein Tools 65400 – Frequently Asked Questions

1) Can Klein 65400 pass through sockets drive nuts on long threaded rod?
That's the whole point of the pass through head. The Klein Tools 65400 KNECT sockets are open through the middle, so threaded rod passes straight through the socket and you can run a hex nut down a rod of any length. A standard deep socket bottoms out on the rod; these don't. Useful for strut hanger rod, seismic bracing, and unistrut threaded rod work on electrical and HVAC installs.
2) Is the Klein 65400 socket set safe to use on an impact wrench?
Yes, it's an impact rated set. The sockets are Chrome-Moly and Chrome-Vanadium, and an impact adapter is included in the kit, with the stated application covering fasteners and impact drivers. Chrome-Moly is the alloy used for impact sockets because it deforms rather than shattering under hammering load.
3) What socket sizes come in the Klein 65400 pass through set?
Eleven SAE hex sizes: 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16 and 3/4 inch. All six point. It's an inch only set, so if you're working metric fasteners this one won't cover you.
4) What exactly is in the 15 piece Klein 65400 kit besides the sockets?
Along with the 11 sockets you get an extension, an impact adapter, a 3/8 inch square adapter, a handle, and the MODbox case. Fifteen pieces total. The handle lets you use it by hand without a separate ratchet, and the square adapter lets you run conventional sockets off the same system.
5) Do I need a 3/8 inch drive tool to use the Klein 65400, and can I use my regular sockets with it?
It's a 3/8 inch drive set, so a 3/8 drive ratchet or impact will run it directly. The included 3/8 inch square adapter also works the other way: it lets you mount standard (non pass through) sockets on the same drive, so you aren't carrying two systems. The 1/4 inch socket doubles as a bit holder for driver bits.
6) How big is the Klein 65400 case and will it fit in a van bin or tool bag?
The case measures 8.75 x 3.7 x 1.8 inches (22.2 x 9.4 x 4.6 cm) and the whole kit weighs 2.22 lbs. Flat and light enough for a bag pocket or a shelf bin.
7) Does the Klein 65400 case stack with other Klein MODbox boxes?
It does. The 65400 case stacks with other MODbox cases and connects to the MODbox Case Adapter Side Rail Attachment, so it rides with an existing MODbox setup rather than floating loose in the truck.
8) Are the Klein pass through sockets 6 point or 12 point?
Six point. That means more contact on the flats of a hex nut and less chance of rounding a corner, which matters when you're running an impact on rusted rod nuts or panel hardware.
