Klein Tools NRHD4 6-in-1 Square Impact Socket
The Klein Tools NRHD4 6-in-1 Square Impact Socket delivers versatile fastening power in a single tool for electricians, utility linemen, and contractors tackling pole-mounted equipment. Two coaxial spring-loaded sockets let you switch between four square sizes — 3/4″, 13/16″, 1″, and 1-1/8″ — without tools, just adjust by hand. The included 7/16″ hex quick-change adapter expands compatibility across 1/2″, 5/8″, and 3/4″ pole hardware. The hollow 13/16″ diameter shaft stretches 6 inches long for deep-set or long threaded bolts. Replacement adapters are available separately.
