Tekton L-key in fastener

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.

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.

Materials and Finishes

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.
Tekton's flat end hex key with laser marking and stamped sizes

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.

Organization Features

Quick Access

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.

Low-Profile Organization

You can also face the L-keys to the side for a flat, low-profile organization solution.

Self-Aligning Key Slots

The slots are uniquely shaped to guide the head of each L-key into alignment with the others.

Durable Material

The holder provides a firm, flexible grip and resists cracking or breaking.
