مفتاح حلقي معزول (VDE) من ساتا قياس (17mm) موديل (ST42417SC)

VDE insulation up to 1000V means the tool has been tested and certified for use around live electrical circuits up to 1000 volts AC, providing an added layer of protection against electric shock when used within its rated range.

The off-corner loading design improves grip and reduces the likelihood of rounding fasteners by applying torque more evenly, especially in situations where fasteners are not perfectly aligned.

Key specs include a 17mm ring size, chrome vanadium steel (Cr-V) construction, a chrome finish for corrosion resistance, an offset head for better access in tight spaces, and a handle marked for easy size identification. It is insulated for use up to 1000V AC.

The handle is ergonomically shaped for a comfortable grip, helping reduce hand fatigue during extended use. It is lightweight for easy maneuverability and prolonged work sessions.

This wrench is suitable for electrical work around live circuits, automotive repairs near electrical components, and general maintenance tasks where 17mm fasteners are encountered and insulation is beneficial.

Wipe the tool clean after use, keep it dry, and store it in a protective case or designated toolbox. Avoid exposure to harsh solvents that could degrade insulation, and periodically inspect the insulation for cracks or wear.

The wrench is designed to meet international safety standards for insulated tools and is rated for use around circuits up to 1000V AC, providing assurance for professional and DIY electrical work.

For similar sizes, consider the 15mm and 19mm SATA insulated wrenches to match your fastener needs. 15mm option: https://fepy.com/products/sata-st42415sc-vde-insulated-single-offset-ring-wrench-15mm. 19mm option: https://fepy.com/products/sata-st42419sc-vde-insulated-single-offset-ring-wrench-19mm. These offer the same VDE insulation and offset design with different fastener sizes for broader capabilities.

The handle is marked with the size, and the 17mm designation is visible on the head and/or handle marking, making it easy to pick the right tool at a glance.

Yes. The precision fit of the 17mm ring and the robust Cr-V steel construction provide secure engagement with fasteners and reliable torque transfer, while the insulated handle adds safety for electrical work. It strikes a balance between precision and durability for professional and DIY use.
