Description

Enhance Your Precision and Leverage with the Klein Tools 7-Piece Magnetic Nut Driver Set

The Klein Tools 647M 7-Piece Magnetic Nut Driver Set is engineered for professionals who demand maximum durability and efficiency on the job. Each driver features a 6-inch chrome-plated hollow shaft, specifically designed to facilitate work on long bolt applications by allowing the bolt to pass through the head. The specialized "donut-shaped" Rare-Earth magnetic tips provide an incredibly secure grip on fasteners, allowing for convenient one-handed operation in tight or overhead spaces. Proudly Made in the USA, these tools are forged to withstand heavy industrial use while providing the reliable performance Klein Tools is known for.

Comfort and torque are paramount with the legendary Cushion-Grip™ handles, which reduce hand fatigue during repetitive tightening tasks while providing the leverage needed for stubborn fasteners. For added longevity, the internal flanges provide a solid, twist-resistant shaft anchor, ensuring the tool remains rigid under high stress. Each handle dome is color-coded for instant size identification in your tool pouch, saving you valuable time on the jobsite. Whether you are working on electrical panels, HVAC systems, or general maintenance, this comprehensive SAE set provides the professional-grade precision required for a flawless finish.
