TEKTON 41-Piece Ball End L-Key Set for Professionals

The TEKTON 41-pc. Ball End Hex and Star L-Key Set features a comprehensive range of commonly used inch hex, metric hex, and star key sizes, all organized neatly in sturdy holders. These holders have self-aligning key slots, allowing for easy removal and insertion of keys without disturbing the others. The L-keys are crafted from 8660 nickel chromium molybdenum steel, which is heat-treated to achieve a hardness of HRC 54-58. This treatment results in tools that offer excellent hardness while remaining resilient, ensuring that they do not become brittle.

When it comes to performance, these L-keys consistently exceed both ASME standards for minimum torsion load and ISO standards for minimum proof torque, providing users with confidence in their strength. Furthermore, they feature a durable manganese phosphate coating that offers resistance against corrosion. Except for the smallest sizes, each L-key is marked in two distinct ways—through high-visibility laser etching and reliable stamped markings—making identification straightforward.

This set contains a total of 41 pieces, including:

• Ball End Hex L-Key Wrenches (13 pcs): Sizes include 0.050, 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 3/16, 7/32, 1/4, 5/16, and 3/8 inches.

• Ball End Hex L-Key Wrenches (15 pcs): Ranging from 1.3 mm to 10 mm, sizes are 1.3, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 7, 8, 9, and 10 mm.

• Star L-Key Wrenches (13 pcs): This set encompasses sizes T6 through T50—T6, T7, T8, T9, T10, T15, T20, T25, T27, T30, T40, T45, and T50.

In addition, the set includes three color-coded holders: a black hex key holder, a red hex key holder, and a gray star key holder.

One of the standout features of the design is the longer keys in the larger sizes, which enhance leverage where it's most needed. This thoughtful addition ensures greater torque application without unnecessary strain. The precise manufacturing of the hex key geometry, particularly at the larger end of the range, leads to a tight fit with fasteners—minimizing play and enhancing control during usage.

Moreover, the L-keys boast a specialized 20-degree ball angle, which increases access to fasteners while maintaining impressive strength. This design ensures that users can reach challenging screws and bolts without compromising torque delivery.

In summary, the TEKTON 41-pc. Ball End Hex and Star L-Key Set provides a robust selection of tools, meticulously engineered for performance, durability, and ease of use. Whether for professional or personal projects, this set promises reliability, making it an indispensable addition to any toolbox.
