Klein Tools KT171HFINS 5-in-1 Hammer Facing Insulated Lineman Wrench

The Klein Tools KT171HFINS 5-in-1 Insulated Lineman Wrench is a 1000V-rated ratcheting hand tool engineered with four square socket sizes and dual integrated striking faces. Certified to ASTM F1505 and IEC 60900 standards, this 25.6 oz forged steel wrench incorporates a 34-tooth ratcheting mechanism with a 10.6-degree swing arc and an open bolt-through design to drive overhead utility hardware, pole crossarm fasteners, and grounding staples in energized environments efficiently.

Best Used For:

  • Pole-Mounted Hardware Fastening: Turning four common utility square bolt sizes (3/4 in., 13/16 in., 1 in., 1-1/8 in.) on distribution crossarms.
  • Energized Utility Line Servicing: Fastening primary distribution hardware safely under 1000V dielectric insulation requirements.
  • Hardware & Staple Driving: Striking pole staples and ground wire molding clips directly using dual-sided forged hammer faces without switching tools.

Key Performance & Safety Features

  • 1000V Certified 3-Shot Insulation: Tested to ASTM F1505 and IEC 60900 standards with a white inner warning layer to alert users when insulation is compromised.
  • Forged Dual Hammer Striking Faces: Machined double-sided hammer faces allow driving hardware pins and staples from either side without tool rotation.
  • 34-Tooth High-Count Ratchet: Delivers a tight 10.6-degree swing arc for fast ratcheting in confined pole-top clearance spaces.
  • Pass-Through Bolt-Through Head: Open socket design allows long threaded utility bolts and studs to extend completely through the socket head.
  • Glove-Compatible Ergonomic Handle: Textured grip provides balanced weight distribution and non-slip control while wearing heavy dielectric rubber gloves.
