Advantages

The Proline CrV 2.5 mm extended hex key offers increased durability due to chrome vanadium construction and a measured hardness of 56–60 HRC. Its extended L-shape and 92 mm overall length provide extra reach compared with standard keys, while the 20 mm working arm allows precise access to confined fasteners. The tool fits standard 2.5 mm hex drive profiles for compatibility with common fasteners.

How to use

Select the Proline 2.5 mm extended L-key and insert the hex tip fully into the fastener recess to ensure a secure fit. Use the long arm for reach and the short arm for greater torque as needed. Apply steady force, keeping the key aligned with the fastener to avoid rounding the hex profile. Combine with compatible wrench handles or a ratchet when required for additional leverage or quicker operation.

Usage recommendations

For best results, keep the hex tip clean and free of debris, avoid excessive torque beyond the fastener’s specification, and store the key in a dry place to prevent corrosion. Inspect periodically for wear before use in precision assemblies.
