Klein Tools 65723 – Frequently Asked Questions
1) Is the Klein Tools 65723 a socket or an extension bar?
It's a 6-inch extension bar, not a socket. It goes between your ratchet and the socket to reach fasteners set down in a recess or behind an obstruction. It has a male square 3/8-inch drive on one end and takes 3/8-inch drive sockets on the other.
2) Will the Klein 65723 extension work with my 1/2-inch drive ratchet?
No. The 65723 is built around a 3/8-inch (9.5 mm) square drive on both ends, so it pairs with a 3/8-inch drive ratchet and 3/8-inch drive sockets. Running it off a 1/2-inch ratchet would take a separate step-down adapter, and running 1/4-inch sockets on it would take a step-up adapter.
3) How much reach does the Klein 65723 add to a ratchet?
Six inches of added reach. That length is enough to clear a panel lip or get down to nuts on a recessed stud inside an enclosure, while still keeping enough feel on the fastener for hand torque.
4) What is the Klein extension bar part number I should order?
Klein Tools 65723. That's the manufacturer part number for the 6-inch, 3/8-inch drive extension, and it's how it's listed on the carton.
5) Is this extension bar going to rust in a truck box or damp panel work?
The bar is forged alloy steel with a chrome-plated finish that Klein calls out as corrosion resistant, so it holds up to the damp and the wipe-downs that come with service work. Chrome also makes grease and drywall dust easy to wipe off before it goes back in the roll.
6) Does the Klein 65723 extension have a knurled section for turning it by hand?
Yes, the bar is knurled so you can spin a fastener down by hand before putting the ratchet on it. Useful when you're starting threads on a panel nut and don't want to cross-thread it.
7) How much does the Klein 65723 extension weigh for a tool pouch?
4.8 oz (136 g). Light enough that it isn't a decision point for a pouch or a service bag, and it'll sit in a standard socket rail or roll.
