Conjunto de chaves KS Tools 512.0218 Competition Double Ring – conjunto de chaves de caixa dupla métricas

KS Tools 512.0218 Competition Double Ring is a metric double-ring spanners set designed for mechanical and maintenance tasks. Each spanner in the set features ring ends on both sides to provide secure engagement with hexagonal fasteners. The set is intended for use in workshops, garages and domestic repair tasks where a precise fit and reliable torque transmission are required.

Advantages

The set delivers uniform contact on fastener faces to reduce rounding and damage. Double-ring ends allow access in confined spaces while maintaining full grip on nuts and bolts. The tools are produced to metric sizes for compatibility with standard European fasteners, offering consistent fit and controlled torque during loosening and tightening operations.

Suitable for

• Automotive maintenance and repair
• General mechanical assembly and disassembly
• Workshop and garage use
• Domestic repairs and DIY projects

Key specifications

• Metric double-ring (box) spanner set
• Ring ends on both sides for secure engagement
• Designed for torque transmission on nuts and bolts
• Intended for workshop, garage and home use

How to use

Select the correct metric size from the set that matches the fastener. Place a ring end fully over the nut or bolt head so the contact surfaces align. Apply steady force to turn the spanner, using the opposite side of the tool or a second spanner for counter-holding if required. Work within the tool’s mechanical limits and avoid sudden impacts that could damage fasteners or the spanner.

Recommendations

Inspect fasteners and spanners prior to use, keep contact surfaces clean, and store the set in a dry place to prevent corrosion. Use the correctly sized spanner to minimise fastener damage and apply controlled force rather than hammering the tool.
