Overview
The Klein Tools 5-in-1 Hammer Facing Insulated Lineman Wrench (KT171HFINS) is a ratcheting lineman wrench with built-in hammer faces and full insulation. This is an insulated lineman wrench designed for utility professionals working pole-mounted hardware in energized environments, combining four square socket sizes and a dual hammer face in one tool.
The 5-in-1 count comes from four square sizes, 3/4", 13/16", 1" and 1-1/8", plus the hammer facing. The hammer faces are forged and machined into the wrench head on both sides, which balances the tool and lets you drive from either side. Klein's point is practical: no rotating the wrench in a bucket to find the striking face means less fumbling and less drop risk.
Insulation is rated 1000V and certified to ASTM F1505 and IEC 60900. Klein uses a three-part (3-shot) insulation with a white under layer that shows through as a warning when the insulation may be compromised, so wear is visible before it becomes a hazard.
The ratchet is reversible with a high 34-tooth count and a 10.6° swing arc for smooth action in confined spaces. The open, bolt-through design passes long bolts and threaded rod, which covers the most common utility hardware. A tether hole supports drop prevention at height.
The steel head has a black phosphate finish, and the redesigned handle is balanced with improved grip texture and compatibility with insulated gloves. Overall length is about 13" (33 cm), and the wrench weighs 1.6 lb (726 g). Who should buy it: linemen and utility crews who want one insulated wrench that ratchets, passes bolts and strikes.

Two machined hammer faces mean no flipping the wrench to tap a bolt home.
