About the Klein Pro 21-Piece Folding Hex Key Set, SAE and Metric - 70552

Your complete hex fastener solution!

The Klein Tools 70552 pro folding hex key set delivers unmatched versatility and control with 21 of the most commonly used SAE and metric key sizes in one compact, easy-to-carry solution. With overall dimensions of 6.6" in length, 1.36" in width, and 2.15" in height, and a combined weight of 32.16 oz (912 g), this rugged 2-piece set is ideal for professionals who need all their essential hex sizes on hand without carrying multiple tools. The set includes extended-reach blades ranging from 3.5" to 4.5" long, making it easier to access fasteners in recessed or tight spaces.

Each hex key is constructed from heat-treated CR-V steel and finished with a corrosion-resistant black phosphate coating for long-lasting performance. The square-cut ends offer a precise, full-depth fit for superior grip inside fasteners, helping prevent slippage and socket stripping—especially important when dealing with worn or stubborn bolts. The independent, high-leverage blade design opens up to 270 degrees, allowing you to maximize torque or maintain control in awkward angles. Open sides on the case provide quick and easy access to outer keys without fumbling.

Moreover, the reinforced orange nylon handle is not only highly visible but also ergonomically shaped for a secure, comfortable grip. A built-in #2 Phillips fastener allows you to adjust the tension of the keys quickly—tighten for stability or loosen for speed, depending on your task. Whether you're working on machinery, bikes, furniture, or automotive components, the Klein Tools 70552 pro folding hex key set combines portability, durability, and function in a compact design ready for professional-grade use.

Klein Tools is more than just a name—it’s the grip that never slips, the durability that withstands the toughest jobs, and the precision that gets it right the first time. Every tool is crafted to feel like an extension of your hand, built for those who demand reliability in the harshest conditions. When the job is on the line, they deliver the performance that keeps you working stronger and longer.

Whether you're assembling equipment, adjusting hardware, or performing precision repairs, this all-in-one set ensures you have the right key at your fingertips.
Reach Tight Spaces Easily: Each key is crafted with extended-reach blades measuring approximately 3.5 to 4.5 inches long, giving you the reach needed to access recessed bolts and tight spots without sacrificing control or torque.
Maintain Optimal Performance: A built-in #2 Phillips fastener lets you fine-tune the blade tension to your preference—tighten for firm positioning or loosen for smoother access. This adjustability adds long-term convenience, preventing loosened blades over time.
Maximize Torque and Comfort: Blades swing independently up to 270°, providing excellent leverage when dealing with stubborn or high-torque fasteners. This flexibility helps you apply more turning power with less effort, especially when space is limited.
Prevent Slipping and Stripping: Each hex key features precision square-cut ends designed for a full-depth, flush fit into fastener sockets. This ensures maximum surface contact to minimize rounding, slipping, and fastener damage during heavy use.
Stay Comfortable Every Time: The reinforced nylon handle is built for strength and control, delivering a comfortable grip even during extended use. Its rugged design offers the durability professionals demand in tough environments.
Provide Rust Protection: Manufactured from tough CR-V steel and finished with a corrosion-resistant black phosphate coating, these keys are engineered to resist wear and rust—offering dependable performance through years of demanding work.
Access Outer Keys Without Obstruction: Convenient openings on each side of the folding case allow quick access to outermost keys without having to unfold the entire set—saving you time when switching between sizes or working in confined areas.
Color-Coded for Fast Identification: Housed in a durable orange case, the compact design keeps keys organized and easy to identify at a glance. It’s small enough to carry in your pocket or pouch but tough enough to take on challenging jobsite conditions.
Complete SAE and Metric Coverage: Includes 11 SAE sizes (3/32" to 1/2") and 10 metric sizes (1.5 mm to 12 mm), giving you everything you need for both imperial and metric fasteners—ideal for professional tradespeople, DIYers, and mechanics alike.
