Klein Tools 646 insulated nut driver 1/2 inch hex 6 inch shank

SKU CH-HXG2-0JKBH

Insulated 1/2-inch hex nut driver with 6-inch hollow shank for live-circuit work

  • Insulated design protects against electric shock
  • 1/2 inch hex tip fits SAE fasteners securely
  • 6 inch shank reaches deep or recessed bolts
  • ESD safe construction prevents static damage
  • Cushion grip reduces hand fatigue during extended use

Insulated 1/2-inch hex nut driver

The Klein Tools 646 insulated nut driver fits a 1/2-inch hex fastener with an 11/32-inch bolt clearance. Its hollow round shank extends six inches to reach recessed hardware. The cushion grip provides comfort and control for electricians and maintenance technicians working on live circuits up to the rated insulation voltage.

Sustained torque on live equipment

The hollow shank slides over long bolts so the tool stays engaged while you apply continuous turning force. Insulation on the shaft protects against accidental contact with energised parts during extended use. The non-magnetic tip avoids attracting metal debris that could bridge conductors in panel work.

Thermals, noise and power draw

Hand-driven operation produces no motor heat, no audible noise and no electrical power consumption. The insulated coating remains stable at typical ambient temperatures encountered in electrical enclosures. ESD-safe materials help prevent static discharge when handling sensitive components.

Questions about this item

Does the insulated nut driver generate any heat or noise during extended use?

As a hand-operated tool, the insulated nut driver produces no heat or noise of its own; only the fastener and the force you apply create sound or warmth.

What drive tool or handle must I already own to use this 1/2-inch hex nut driver?

The 1/2-inch hex tip fits directly onto a 1/2-inch square-drive ratchet, impact wrench or T-handle; no additional adapter is required.

Will the 6-inch shank reach fasteners in the same tight spaces as my older 3-inch nut drivers?

The longer 6-inch shank provides deeper reach but needs more clearance; it will not fit where a shorter 3-inch shank was previously used.
