مفتاح حلقي معزول (VDE) من ساتا قياس (7mm) موديل (ST42407SC)

VDE insulation indicates the tool is rated for up to 1,000 volts, providing protection against electric shocks when working on live circuits and meeting recognized safety standards for insulated tools.

Key features include off-corner loading for better grip and reduced rounding, an offset box end for tight-space access, chrome vanadium steel construction for strength, a corrosion-resistant chrome finish, and an ergonomic handle for comfortable use.

Size: 7mm. Insulation rating: 1,000 V AC. Material: Chrome vanadium steel (Cr-V). Finish: Chrome for rust resistance. Design: Offset head with off-corner loading.

Inspect the tool for damage before use, wear appropriate PPE, work within the rated voltage (up to 1,000 V AC), avoid using if insulation is damaged, keep hands dry, and use the correct size with steady torque to minimize rounding.

It is designed to fit 7mm fasteners. Look for size markings on the handle to confirm the correct size, and apply controlled torque to avoid rounding.

Constructed from chrome vanadium steel with a chrome finish, it is designed for high strength, long life, and corrosion resistance in typical use.

Electrical installations and maintenance, automotive repairs, and general maintenance tasks where insulated tools help protect against electric shock and where access in tight spaces is needed.

Clean it with a dry cloth after use, avoid exposure to moisture, store in a dry toolbox, and inspect for any damage before each use to ensure insulation integrity remains intact.

Yes. The VDE insulation up to 1,000 V AC and durable chrome vanadium construction make it suitable for both professional electrical work and DIY tasks involving live circuits.

The 7mm VDE insulated wrench provides electrical protection up to 1,000 V AC, reducing shock risk when working near live circuits. The off-corner loading and offset design also improve accessibility and reduce fastener damage compared with non-insulated tools.
