Knipex 98-00-10 insulated open end wrench 10 mm tool storage

Insulated 10 mm open-end wrench

This Knipex open-end wrench is insulated to 1000 V AC and complies with IEC 60900 and DIN EN 60900. It is built from alloy steel with chrome vanadium material for durability. The 10 mm head size fits a range of metric fasteners. It is suited for electricians and technicians working on live or potentially live low-voltage equipment.

Practical limits of 1000 V AC insulation

The insulation rating covers work up to 1000 V AC under the cited standards. It does not extend protection beyond that voltage or to other hazard categories not defined by IEC 60900. The open-end profile requires sufficient clearance around the fastener and cannot apply torque as securely as a ring or socket. Buyers needing higher voltage ratings, different head profiles, or insulated sets for comprehensive coverage should look elsewhere.

Replaces non-insulated 10 mm wrenches

This wrench replaces a standard non-insulated 10 mm open-end wrench when electrical insulation is required by safety regulations. The jump is worth it whenever work involves exposure to live parts up to the rated voltage. It is not a substitute for a complete insulated tool kit, a torque wrench, or a ring spanner where those are specified.
