Product Details
The TEKTON L-key set features high leverage with longer keys designed to increase torque where it matters, ensuring a tight fit with fasteners by precisely manufacturing hex key geometry on the large end of the applicable range to reduce slop. Tolerances are controlled in two ways—point-to-point and side-to-side—maintaining high dimensional accuracy and consistency. The keys have refined edges with slightly chamfered sides (except for sizes 1.3 mm, 1.5 mm, 2 mm, 0.050 in., 1/16 in., and 5/64 in.) and smooth top faces for optimized fastener engagement. Made from 8660 nickel chromium molybdenum steel heat-treated to 54-58 HRC, these L-keys provide maximum torque strength that consistently exceeds ASME minimum torsion load and ISO minimum proof torque standards. They are coated with a durable manganese phosphate finish resistant to corrosion, tested by a 45-hour submersion in 1% saltwater after cleaning with isopropyl alcohol. With clear size markings in both high-visibility laser and stamped formats (except the smallest sizes), the set includes a specially designed holder that organizes the L-keys facing forward for quick access or sideways for low-profile storage, featuring self-aligning key slots to guide each key into alignment. The holder is made from durable material, providing a firm and organized storage solution. The set meets or exceeds relevant certification and compliance standards and includes a warranty to ensure long-lasting performance.
