Ratchet Wrench KS Tools 503.5205 Chromium-vanadium Steel 72 pcs

The KS Tools 503.5205 ratchet wrench set is manufactured from chromium-vanadium steel and includes 72 ratchet heads designed for secure and efficient fastening. Certified to DIN 3113 and ISO 3318 standards, the set aims to deliver consistent performance and dimensional accuracy across a wide range of fastening tasks. Each sales pack contains five pieces and the tool pack is engineered to balance durability with manageable weight for both workshop and home use.

Advantages

The chromium-vanadium steel construction provides high tensile strength and resistance to wear, while the ratcheting mechanism with 72 teeth allows for fine incremental movement and reduced handle swing in confined spaces. Compliance with DIN 3113 and ISO 3318 confirms controlled tolerances and interchangeability. The set’s balanced weight supports prolonged use without excessive fatigue, and the individual pieces are suitable for precise torque application and repeated operations.

Suitable for

• Automotive repair and maintenance tasks
• Mechanical assembly and disassembly work
• General household fastening and plumbing jobs
• Professional workshops requiring standards-compliant hand tools

• Pack contents: 5 pieces per pack
• Net weight (per pack): 661 g

How to use

Select the correctly sized ratchet head for the fastener and attach it securely to the wrench. Position the wrench squarely on the fastener head and apply steady force to turn in the desired direction; use the ratchet direction switch if equipped to change between tightening and loosening. For work in tight spaces, use the fine 72-tooth ratchet increments to reduce handle movement and maintain control. After use, clean off dirt and residues and store the pieces dry to prevent corrosion.

Recommendations

Inspect heads and the ratchet mechanism periodically for wear and ensure fasteners are engaged squarely to avoid rounding. Use appropriate safety equipment and avoid applying impact force with this hand tool; for high-torque applications consider a specialist torque tool.
