Juego de llaves de estrella y fijas ks tools 512.0215 — medidas métricas juego (512.0215)

ks tools 512.0215 is a set of metric ring and combination wrenches designed for general mechanical and maintenance work. The set combines closed-ring wrenches and open-end combination wrenches in commonly used metric sizes, delivering precise fit to fasteners, effective torque transmission and durable construction for repeated workshop and field use. The tools are intended to support automotive repairs, industrial maintenance and domestic tasks where reliable hand tools are required.

Advantages

The ring and combination wrench set offers accurate jaw and ring profiles that reduce rounding of nuts and bolts and provide stable engagement under load. Hardened and tempered steel construction ensures wear resistance and long service life while machined surfaces and clear size markings enable quick identification and handling. The combination of open-end accessibility and ring-end torque capability provides versatility for different fastening situations.

Suitable for

• Automotive repair and maintenance
• Industrial equipment servicing
• Home and DIY mechanical tasks
• On-site field maintenance and installations

Key specifications

• Metric sizes included: a range of common metric wrench sizes (set configured as metric combination and ring wrenches)
• Material: hardened and tempered alloy steel for strength and wear resistance
• Finish: machined/chrome or satin finish for corrosion resistance and easy cleaning
• Design: combination wrenches with open-end and ring-end of matching size; ring ends for full-contact torque
• Markings: clear size markings on each wrench for fast identification

How to use

Select the wrench matching the metric fastener size, ensuring a snug fit on the nut or bolt before applying force. Use the open end where quick placement or working in tight spaces is required; use the ring end when higher torque or safer multi-point engagement is needed. Apply steady, controlled force and avoid sudden impacts with hand wrenches. Maintain correct body posture and tool alignment to reduce slippage and protect fastener heads.

Recommendations

Inspect wrenches for wear or damage before use and replace any badly worn tools. Keep tools clean and lightly lubricate pivot or storage areas to prevent corrosion. For high-torque applications, use appropriate torque tools rather than relying solely on hand wrenches. Store the set in a dry place and use size-organized racks or pouches to preserve markings and finish.
