Wrench Proline CrV 10 mm extended — Proline 10mm chrome vanadium extended wrench

Proline CrV 10 mm extended L-type hex wrench is made from chrome-vanadium steel with a hardness of 56–60 HRC. With an overall length of 170 mm and a short leg of 40 mm, this 10 mm hex key provides extended reach and improved leverage for working on recessed or hard-to-access fasteners.

Advantages

Manufactured from chrome-vanadium (CrV) steel for durability and resistance to wear, the wrench’s specified hardness ensures reliable torque transmission and reduced risk of deformation. The extended L-shape and longer leg length increase reach and leverage compared with standard hex keys, improving access to tight spaces while maintaining compact handling.

Suitable for

• Automotive repair and maintenance
• Equipment assembly and mechanical work
• Home DIY and general workshop tasks

How to use

Select the 10 mm hex end that fits the fastener securely.

Apply steady, even force to avoid rounding the fastener head and ensure the wrench is fully seated before turning.

Usage recommendations

For best results, keep the wrench clean and free of oil or debris; store in a dry place to prevent corrosion. Avoid using cheater bars or excessive impact on the tool beyond its rated capacity to prevent damage.
