Socket wrench Proline CrV 8 mm extended – 8mm chrome vanadium extended socket wrench

Extended L-type hex key in 8 mm size, manufactured from chrome vanadium (CrV) steel with a hardness of 56–60 HRC. The tool measures 149 mm overall with a 36 mm working length and is designed to reach recessed or hard-to-access fasteners. It is a single-size, compact socket wrench intended for tightening and loosening bolts and nuts where a standard-length hex key is insufficient.

Advantages

The Proline CrV 8 mm extended socket wrench is made from chrome vanadium steel for increased strength and wear resistance. Its hardened construction (56–60 HRC) provides durability under torque, while the extended L-shape and 149 mm length allow access to deep or recessed fasteners. The single-piece design ensures reliable transfer of force and reduces the risk of rounding fastener heads.

Suitable for

• Automotive repair and maintenance
• Workshop and mechanical assembly tasks
• Household repairs where fasteners are recessed or hard to reach
• Professional technicians needing a compact, single-size hex tool

How to use

Select fasteners with an 8 mm hex socket and insert the short or long arm of the L-key into the fastener as needed to achieve leverage. Apply steady torque, using the longer arm for greater leverage and the shorter arm for confined spaces. Ensure proper seating of the hex key in the fastener to avoid slipping and rounding. After use, store the tool in a toolbox or holder to prevent corrosion and damage.

Usage recommendations

Use the extended Proline CrV 8 mm hex key for tasks that require reach into recessed areas. Avoid excessive impact or use with cheater bars beyond the tool's rated capacity. Keep the tool clean and dry; apply a light lubricant if storage in humid conditions is necessary.
