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.

Key Features

  • Full Hollow Shafts: Facilitates work on long bolt applications (except 3/16" size).
  • Rare-Earth Magnetic Tips: High-strength magnets securely hold fasteners in place for easy use.
  • Cushion-Grip™ Handles: Ergonomic design provides superior comfort and maximum torque for all-day use.
  • Twist-Resistant Anchor: Internal handle flanges provide a rock-solid blade connection that won't slip under load.

HP G5 Dock Mount
Works as advertised! I purchased this as a test piece for our office supplied computers. It frees up space in the desk nd hides unsightly cords from view. I have it wall mounted behind the monitors and am very pleased thus far!

Necessity
After the disorganization of my working space drove me crazy, I did an overhaul. This was one of the additions that I bought to not only give me more space but also allow for better cable management. I mounted mine under my desk, which let me contain the cable chaos beneath the desk.

Fits great.
Multiple iterations of this dock have wires coming out both the front and back, making it ugly on the desk and no way to hide wires well. Mounting under the desk with this helped a ton, looks way better. Perfect fit.

High-quality, high-value
Color: Black, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
I was looking for something similar for my Uplift Desk for a long time, and gave up until I built a new computer and had a reason to resume the search. Seriously, this desk mount is top-tier; I'm coming out of a long drought to review this product. The build quality, strength and stability is impressive, and assembly is easy. I'm confident that the stand could hold my body weight, let alone a computer. The appearance of the finish is high-quality, and color matches the coated steel frame of the Uplift desk flawlessly. In terms of possible areas of improvement, I'd love to see a tighter vertical fitment of the top bracket's sliding arm, and I'd love if there were more rubber anti-slip pads and spacers of different shapes and sizes included. I ended up double-stacking the anti-slip pads, using superglue to adhere them to each other, to give my PC more breathing room on its underside. I'd also love to have the option to select different sizes of base plates.
