Wiha 21022 Insulated Offset Box End Wrench 22 Mm

Product Description

The WIHA 21022 is a single-end, 6-point offset box end wrench rated for insulated electrical work. It is built from chromium-vanadium steel and features a 15-degree head offset angle that provides knuckle clearance in tight spaces. With an overall length of 257 mm (approximately 10.1 inches), this wrench delivers the leverage needed for 22 mm fasteners in panel, switchgear, and industrial electrical installations. It carries certifications to CSA, EN/IEC 60900, ASTM F1505, and NFPA-70E, making it a code-compliant choice for live electrical work up to the rated voltage of those standards. Licensed electricians and industrial maintenance technicians are the primary installers.

This wrench is suited for residential, commercial, and industrial electrical applications where insulated tooling is required by code or safety protocol. The 15-degree offset head allows access to recessed fasteners inside enclosures, panels, and motor terminals. The 6-point box end provides full contact on hex fasteners, reducing the risk of rounding. It is a non-ratcheting, single-end design intended for straightforward torque application where a controlled, deliberate motion is preferred.

Key Features

• Insulated construction meets CSA, EN/IEC 60900, ASTM F1505, and NFPA-70E standards for live electrical work
• Chromium-vanadium steel construction for strength and corrosion resistance
• 15-degree head offset angle provides knuckle clearance in confined spaces
• 6-point box end maximizes contact on hex fasteners to reduce rounding
• Single-end, non-ratcheting design for controlled torque application
• Overall length of approximately 10.1 inches for reach and leverage

Compatibility

Designed for use with 22 mm hex fasteners in insulated-tool applications governed by EN/IEC 60900, ASTM F1505, CSA, and NFPA-70E requirements.

Installation Notes

This tool is intended for use by licensed electricians working on or near energized equipment where insulated tooling is required. Before beginning any service, follow lockout/tagout procedures in accordance with NFPA-70E unless the specific task requires energized work authorization. Inspect the insulation for cracks, cuts, or damage before each use — a compromised insulated tool must be removed from service immediately. Consult applicable electrical codes, including the NEC, before performing work on energized conductors or equipment.
