مفتاح حلقي معزول (VDE) من ساتا قياس (16mm) موديل (ST42416SC)

The VDE insulation rating indicates protection against electric shock when working on live circuits up to 1,000 V AC. Use it for tasks within that voltage range and follow standard electrical safety practices. It does not make the tool suitable for all high-voltage scenarios or as a replacement for other safety equipment.

Key features include an offset box end for better access to recessed fasteners, off-corner loading to improve grip and reduce rounding, chrome vanadium (Cr-V) steel for strength, a corrosion-resistant chrome finish, an ergonomic handle for comfort, and markings on the handle for quick size identification.

Size: 16mm. Material: Chrome vanadium steel (Cr-V). Finish: Chrome for corrosion resistance. Insulation: VDE-rated up to 1,000V AC. Design: Offset head with off-corner loading. Identification: Size markings on the handle. Use-case: Electrical work, automotive maintenance, and general tasks in confined spaces.

Use it when you need to tighten or loosen 16mm fasteners in electrical or automotive environments, especially where space is tight and access is restricted. It’s useful for live-circuit work within its voltage rating and for tasks that benefit from reduced fastener rounding and a comfortable grip.

Wear appropriate PPE and follow standard electrical safety practices. Hold the tool by the insulated handle, apply torque to the fastener without forcing it, and avoid contact with conductive parts outside the insulated grip range. Do not use for hammering or as a pry tool.

The 16mm version matches medium-size fasteners in the range covered by the ST424SC family. For smaller fasteners, the 12mm or 14mm versions offer closer fits, while larger sizes like 18mm or 20mm are designed for bigger fasteners. Each size maintains VDE insulation and the same design principles (offset head, off-corner loading, Cr-V construction). For precise size differences, you can compare the 12mm, 14mm, 18mm, and 20mm variants on Fepy.

You can compare similar VDE-insulated wrenches in the SATA ST424 SC range, such as the 12mm version: https://fepy.com/products/sata-st42412sc-vde-insulated-single-offset-ring-wrench-12mm, the 14mm version: https://fepy.com/products/sata-st42414sc-vde-insulated-single-offset-ring-wrench-14mm, the 18mm version: https://fepy.com/products/sata-st42418sc-vde-insulated-single-offset-ring-wrench-18mm, and the 20mm version: https://fepy.com/products/sata-st42420sc-vde-insulated-single-offset-ring-wrench-20mm.

The wrench has size markings on the handle. Look for the 16mm indicator to confirm the size before use, ensuring you apply torque to the correct fastener and maintain proper fit to minimize rounding.

Wipe the tool with a clean, dry cloth after use to remove oils and dirt. Avoid harsh solvents that could damage the insulation. Store in a dry place to protect the chrome finish and keep the Cr-V core from corrosion.

Yes. While it is designed for electrical work with its insulation, the 16mm wrench can be used for general fastener work in automotive and maintenance tasks, provided the fastener is 16mm and within the tool’s mechanical capacity.
