Flat wrench 12 mm 1000V, NEO tools model 01-116 — insulated single-sided hand tool

NEO tools flat wrench 12 mm (model 01-116) is a single-sided insulated hand tool designed for work on electrical installations up to 1000 V. The tool has a 12 mm opening sized for nuts and bolts commonly found in electrical equipment and terminal blocks. Insulation around the working end and handle reduces the risk of electric shock, making the wrench suitable for tasks that require contact with live or potentially live conductors when used according to safety rules.

Advantages

The insulated flat wrench provides electrical protection rated to 1000 V while maintaining the mechanical strength required for tightening and loosening fasteners. Its single-sided open end allows access in tight or constrained spaces where boxed or socket tools cannot reach. The tool combines clear size marking and an ergonomic handle profile to support controlled torque application and comfortable handling during extended use.

Suitable for

• Installing and removing nuts on terminal blocks and electrical panels
• Maintenance of electrical motors, switches and distribution boards
• Work in confined spaces where an open-end wrench is required
• Field service and on-site electrical troubleshooting

Key specifications

• Wrench opening: 12 mm
• Tool type: single-sided open-end (flat) wrench
• Insulation: protective insulated coating rated for up to 1000 V
• Intended use: hand tool for electrical work on live or de-energized circuits (follow safety procedures)
• Typical applications: electrical connectors, terminal screws, small fasteners in panels and enclosures

How to use

Select the 12 mm flat wrench when the fastener head matches the wrench opening. Verify that the insulation is intact and free of damage before use. When working near live conductors, follow applicable safety standards and wear required personal protective equipment. Position the open end of the wrench fully over the nut or bolt head, apply steady force in the direction needed to tighten or loosen the fastener, and avoid sudden jerks. After use, inspect the insulation surface and store the tool in a clean, dry place away from direct sunlight and chemicals that could degrade the insulating material.

Usage recommendations

Use the wrench only within its insulation rating and for the intended hand-tool tasks. Do not use the tool as a hammer, pry bar, or on fasteners larger than its 12 mm opening. Replace the tool if insulation shows cracks, cuts, or other damage; periodic visual checks and compliance with workplace electrical safety procedures are recommended.
