Four-way wheel nut wrench ELORA 195CV, hexagon sockets for automotive workshops

Four-way wheel nut wrench ELORA 195CV integrates four hexagon sockets into one cross-shaped tool. Technicians select the correct size without changing equipment. Chrome-Vanadium steel 31CrV3 provides hardness and load capacity. Matt chrome surface protects against rust in harsh workshop environments. The 380 mm length generates sufficient leverage for tight fasteners. Weight of 1300 g ensures stable grip during operation.

DIN 3119 and ISO 6788 compliance guarantees dimensional accuracy and load-bearing performance. Heat treatment maintains consistent hardness over extended use. The six-point hexagon profile distributes torque evenly across nut faces. This design minimizes the risk of rounding corners under high load.

Construction and material of the four-way wheel nut wrench

Chrome-Vanadium steel 31CrV3 (material number 1.2208) forms the core structure. Controlled heat treatment achieves the required hardness range. Matt chrome plating covers all surfaces to prevent oxidation. The four-arm layout allows steering-wheel-style rotation for smooth torque application. Arm spacing is calculated to clear brake discs and wheel spokes.

• Material: Chrome-Vanadium steel 31CrV3 / 1.2208
• Surface finish: Matt chrome plating
• Socket profile: Six-point hexagon
• Configuration: Four-arm cross design
• Standards: DIN 3119, ISO 6788
• Overall length: 380 mm
• Weight: 1300 g

The cross configuration distributes user force across two opposing arms. This balance reduces hand fatigue during repetitive wheel changes. Socket depth accommodates standard automotive wheel studs. The tool remains compact enough for storage in vehicle trunks or service van compartments.

Socket size options

Model 195CV-17 includes 17 mm, 19 mm, 22 mm and 11/16 inch sockets. Model 195CV-5/8 offers 5/8 inch, 11/16 inch, 3/4 inch and 7/8 inch sockets. Users choose the variant matching their most common wheel nut sizes. Each socket is permanently integrated into one arm of the cross.

• 195CV-17: 17 mm, 19 mm, 22 mm, 11/16 inch
• 195CV-5/8: 5/8 inch, 11/16 inch, 3/4 inch, 7/8 inch
• Socket type: Hexagon (six-point)
• Drive configuration: Fixed sockets on four arms

Hexagon sockets grip all six flats of the nut simultaneously. This full contact reduces stress concentration at individual corners. The fixed-socket design eliminates the need for separate drive adapters or loose socket sets during roadside tire changes.

Standards and quality assurance

DIN 3119 specifies dimensional tolerances for socket wrenches. ISO 6788 defines test methods for hand-operated socket tools. Both standards ensure interchangeability with fasteners manufactured to metric and imperial norms. Heat treatment follows controlled temperature cycles to achieve uniform hardness distribution.

• DIN 3119: Dimensional and tolerance requirements
• ISO 6788: Performance and testing specifications
• Heat treatment: Controlled quenching and tempering
• Hardness: Maintained across working surfaces

Matt chrome finish undergoes thickness and adhesion testing. The coating protects the steel substrate from moisture and road salt. Regular inspection during production verifies socket wall thickness and corner radius to prevent premature wear.

Common applications

Automotive workshops use this wrench for tire rotation and seasonal wheel changes. Roadside assistance operators carry it for emergency flat-tire repairs. Private vehicle owners store it in the trunk for self-service tire replacement. Light commercial vehicles and agricultural machinery with matching nut sizes also benefit from the tool. The four-socket layout reduces the number of tools required in mobile service kits. Cross-arm design allows two-handed operation for maximum torque when loosening corroded fasteners.

Technical reference

Chrome-Vanadium steel 31CrV3 contains chromium and vanadium alloying elements. Chromium enhances corrosion resistance and hardenability. Vanadium refines grain structure for improved toughness. Material number 1.2208 corresponds to the European steel designation system. The 380 mm length provides a moment arm suitable for typical wheel nut torque specifications. Weight of 1300 g balances portability with structural rigidity. Matt chrome plating thickness meets automotive tool industry standards for abrasion resistance.
