Κλειδί πολύγωνο-ανοιχτό KS Tools 503.4213 13 mm χάλυβας χρωμίου-βαναδίου

The KS Tools 503.4213 13 mm combination wrench is manufactured from chromium-vanadium steel to provide a balance of strength and corrosion resistance for everyday mechanical work. Conforming to DIN 3113 and ISO 3318 standards, the tool combines an open-end jaw and a ring end in a single 178 mm-long format, weighing approximately 80 g, which makes it compact and easy to operate in tight spaces.

Advantages

This 13 mm combination wrench offers durable construction due to its chromium-vanadium alloy, delivering reliable torque transfer and wear resistance for repeated use. The dual-ended design enables quick switching between open and boxed engagement without changing tools. Its length and weight provide a controlled grip and sufficient reach for common fastening tasks while remaining portable in tool kits.

Key specifications

• Size: 13 mm
• Material: Chromium-Vanadium steel
• Standards: DIN 3113, ISO 3318
• Length: 178 mm
• Weight: approx. 80 g
• Design: Combination wrench (open-end and ring end)

How to use

Select the 13 mm end that matches the fastener head, position the open jaw or ring over the bolt or nut, and apply steady force in the required direction. Use the ring end for greater surface contact and reduced rounding on hex heads, and the open end for quick engagement in confined spaces. Ensure correct orientation to avoid slipping and apply controlled torque appropriate to the fastener and material.

Recommendations

Inspect the wrench for damage or excessive wear before use. Keep the working surfaces clean and free of oil for secure grip. Store the wrench in a dry place to minimize corrosion and pair it with appropriate torque measuring tools when working on components that require specific torque settings.
