Specifications
- Brand: Tekton
- Model: KLX12625
- Product Type: Flat end hex L-key
- Size: 5/8 inch
- Range coverage: 7/16–3/4 inch (11–19 mm series)
Materials and Build
Made from heat-treated 6150 chromium-vanadium steel at 44–50 HRC — hard without being brittle — and finished with a corrosion-resistant manganese phosphate coating.
Functions and Leverage
The largest sizes are lengthened for extra leverage where it matters most, so stuck large fasteners turn with less strain.
Fit and Tolerances
Tekton measures tolerances point-to-point and side-to-side, and chamfers edges for smooth, precise engagement with hex socket fasteners.
Size Markings
High-visibility laser marking plus a stamped marking keep the size readable for the life of the tool.
Use Cases
- Automotive and heavy equipment repair
- Large hex-socket bolts on machinery and outdoor equipment
- General shop and home maintenance

Compared to generic L-keys, the KLX12625 offers verified dimensional accuracy, harder 6150 steel, and dual markings. If you need other sizes in the 7/16–3/4 inch range, pair this key with additional Tekton flat end L-keys.
