مفتاح حلقي معزول (VDE) من ساتا قياس (11mm) موديل (ST42411SC)

It means the tool is designed and tested to protect the user from electric shock when used on live circuits up to 1000 V AC. Always inspect the insulation for damage and retire the tool if the insulation is nicked or worn.

The off-corner loading design concentrates contact on the fastener corners to reduce rounding, while the offset head provides better access to fasteners located in tight or recessed spaces.

Material: chrome vanadium steel (Cr-V); Finish: chrome; Size: 11 mm; Insulation: rated for up to 1000 V AC; Design: offset box end with off-corner loading; Ergonomic handle; lightweight and durable construction.

Electrical work on live or partially-de-energized circuits up to 1000 V, automotive repairs, and general maintenance tasks where an insulated tool with access to recessed fasteners is beneficial.

Use it only on 11 mm fasteners within its torque rating, inspect the insulation and chrome finish before each use, clean after use, keep it dry, and store in a dry place away from chemicals that could degrade the insulation.

The handle is designed for a comfortable grip to reduce hand fatigue during extended use, with markings for quick size identification to speed up tool selection.

For other sizes in the same family, you can explore the 10 mm and 12 mm insulated variants to fit different fastener sizes. Compare features like insulation rating, offset design, and Cr-V construction across models. Example alternatives:
