SATA ST42417SC VDE Insulated Single Offset Ring Wrench 17mm

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.
