Features:

• High Leverage: We designed the keys to be longer in the largest sizes to increase leverage where it matters.
• Tight Fit with Fasteners: We precisely manufacture our hex key geometry on the large end of the applicable range. resulting in less slop in fasteners.
• Two Measures of Tolerance Control: We measure our hex key tolerances in two ways. from point-to-point and side-to-side. to ensure the highest standards of dimensional accuracy and consistency.
• 20¼ Ball Angle Increases Access: Our keys implement a steep ball end angle that increases your ability to access fasteners while still maintaining sufficient strength.
• Refined Edges: Tekton keys have slightly chamfered edges (except sizes that are too small to be chamfered: 1.3 mm. 1.5 mm. 2 mm. 0.050 in.. 1/16 in.. and 5/64 in.) and a smooth top face to optimize engagement with fasteners.
• Maximum Torque Strength: We make our L-keys with 8660 nickel chromium molybdenum steel that's heat-treated to 54-58 HRC to produce tools that are hard. but not brittle. As a result. the maximum torque of the L-keys consistently exceeds the ASME standards for minimum torsion load and the ISO standards for minimum proof torque.
• Corrosion-Resistant Finish: We coat all of our keys with a durable manganese phosphate finish that's resistant to corrosion.
• Clear Markings: With the exception of the smallest sizes. Tekton L-key sizes are marked in two ways-both with a high-visibility laser marking and a stamped marking.
• We designed the holder to organize the L-keys facing forward so you can easily access each tool without having to move others out of the way. You can also face the L-keys to the side for a flat. low-profile organization solution. The slots are uniquely shaped to guide the head of each L-key into alignment with the others. The slots are uniquely shaped to guide the head of each L-key into alignment with the others. The holder provides a firm. flexible grip and resists cracking or breaking.
