Klein Tools NRHD 5-in-1 Impact Socket - 3/4", 1", 1-1/8" Square, 7/16" Hex Adapter

The Klein Tools NRHD Impact Socket (the 3-in-1 for its three square sizes, now called the 5-in-1 by Klein for its added alignment slots) puts the three most common utility socket sizes in one tool, so you can move between pole hardware without digging through your bag. A quick twist converts the socket between 3/4-Inch, 1-Inch, and 1-1/8-Inch square openings, covering the fasteners linemen hit most in distribution work. The included 7/16-Inch hex quick-change adapter drops straight into your impact driver, and a fine-tuned ball tip keeps the socket seated on the anvil to minimize drops when you are working off a bucket or hooks.

The 13/16-Inch diameter hollow shaft runs 6-Inches deep, letting the socket pass over long threaded bolts and double-arming hardware that stops a standard socket cold. At 24 oz (680 g) of impact-rated steel, the NRHD replaces three dedicated sockets with one that stays on the driver.
