Knipex 98 00 13 open-end wrench 13 mm 15° insulated

13 mm insulated open-end wrench

This Knipex wrench is a single-end, metric hand tool made from alloy steel with a chrome finish. Its 13 mm head is set at a 15-degree angle and measures 1/4 inch thick, while the overall length is 5 1/8 inches. The rounded, one-piece construction includes full insulation for work on live electrical components up to the rated voltage. Professional electricians and maintenance technicians reach for it when a slim, insulated profile is required.

Suited for electrical panel work

The insulated, single-end design fits confined spaces around busbars, breakers and control wiring where a non-insulated or double-ended wrench would be unsafe or too bulky. Buyers who need a ratcheting mechanism, a box-end profile or a set covering multiple sizes should look at other tool configurations. The fixed 13 mm opening also means it cannot replace an adjustable wrench for varied fastener dimensions.

Consistent performance during prolonged use

The one-piece alloy steel body resists flexing when torque is applied repeatedly, so the head geometry stays true across long service intervals. Chrome plating protects the surface from corrosion in humid plant environments without adding measurable thickness. Insulation remains bonded to the steel through normal heating and cooling cycles, preserving dielectric integrity shift after shift.
