Klein Tools 65239 – Frequently Asked Questions

1) Will the Klein 65239 impact socket set work with my 3/8-inch impact ratchet, or do I need a Klein driver?
Any standard 3/8-inch square drive ratchet drives this set. The Flip-20 sockets run on 1/4-inch and 3/8-inch square drive, and the included square drive adapter mates to a common 3/8-inch ratchet as well as to the Klein pass-through socket wrench. You do not need to be in the Klein KNECT ecosystem to use it, though the adapters are what tie it into that system.
2) How does a 13-piece set cover 20 socket sizes?
Ten of the thirteen pieces are flip sockets, and each one carries two sizes, one on each end, for 20 SAE and metric sizes total. The SAE pairings are 1/4 x 5/16, 3/8 x 7/16, 1/2 x 9/16, 5/8 x 3/4 and 11/16 x 13/16 inch; the metric pairings are 8 x 10, 9 x 11, 12 x 14, 13 x 15 and 16 x 18 mm. The remaining three pieces are two nested adapters and an extended shaft, and the sockets are color coded so you can pick a size by sight instead of reading stamps in a dark panel room.
3) Are the sockets in the Klein Flip-20 set actually impact rated, or just chrome sockets in a case?
Impact-rated steel, not chrome. That matters because a chrome hand socket can crack under an impact gun. This set is built for driving hex fasteners under impact, which is what you want for panel mounting, strut and conduit support brackets, and equipment anchors.
4) Will the Klein Flip-20 sockets reach down a long threaded rod or a stud that sticks out past the nut?
Yes, these are deep well sockets, which is the reason they suit electrical work: all-thread hanging conduit and strut, long anchor studs, and equipment bolts where a standard-depth socket bottoms out on the protruding thread before it seats on the nut.
5) How big is the Klein 65239 case and will it fit in a van drawer or a tool bag pocket?
The case measures 9.25 inches long by 5.25 inches wide by 1.63 inches high and the whole set weighs 2.93 pounds. That flat profile is the point of the Flip-20 design, a 20-size range in something that lies down in a drawer or a bag pocket instead of a full socket tray. The lid is clear so you can see what is in it, and it works with the Klein MODbox modular storage.
6) What is the stacking feature on the Klein KNECT Flip-20 set and which sizes stack?
Six of the smaller sockets, covering 1/4 inch through 9/16 inch and 8 through 14 mm, stack onto the adapter so you can carry a working range on one shaft and change sizes without going back to the case. On a lift or in a ceiling that is the difference between one trip up and several.
7) Do I need to buy anything else to use the Klein 65239 impact socket set?
You need a driver. The set ships with 10 flip sockets, 2 nested adapters, an extended shaft and the case; it does not include a ratchet or impact gun. Any 3/8-inch square drive ratchet or impact driver works, and the extended shaft plus adapters are what let the sockets run on Klein KNECT drivers. There is also a small parts tray inside the case for loose fasteners and washers.
8) Is the Klein Flip-20 set a good choice for a fleet or crew standardizing on one socket kit?
For electrical and MRO crews, yes, and for one specific reason: it carries both SAE and metric in a single 2.93 pound case, so a tech does not have to decide which set to grab for a service call. Color coding cuts the mix-ups that come with shared kits. Where it is the wrong call is a shop working heavy mechanical hardware above 13/16 inch or 18 mm, which is the top of this range; that work wants a full 1/2-inch drive impact set instead.
9) What is the Klein model number for the 13-piece KNECT Flip-20 impact socket set?
Klein Tools 65239. That is the 13-piece Flip-20 impact socket set covering SAE and metric on 1/4-inch and 3/8-inch drive. Ordering by 65239 gets you the set with the 10 flip sockets, both adapters and the modular case, as opposed to the individual flip sockets Klein sells loose.
