Avainsarja Hazet 450N/10 – yhdistelmäavaimet, kromi-vanadiini, 10 osaa

Hazet 450N/10 is a set of 10 double open-ended wrenches made from chrome vanadium steel. Each wrench features two open ends with different sizes, providing immediate access to fasteners without removing the tool. The set is intended for general mechanical and automotive work and combines solid torque transfer with corrosion-resistant finish for frequent workshop and field use.

Advantages

The chrome vanadium construction ensures a balance of strength and toughness while maintaining a relatively low weight. Double open-ended design saves time on repetitive tasks and in tight spaces where switching tools is impractical. A corrosion-resistant surface finish extends service life and keeps the contact surfaces clean to preserve reliable torque transfer. The standardized sizing across the ten pieces allows quick selection and reduces the need for additional tools.

Suitable for (tasks / use cases)

• Automotive maintenance and repair
• General mechanical assembly and disassembly
• Light industrial and maintenance work
• On-site field service where compact, versatile tools are required

Key specifications

• Set composition: 10 double open-ended wrenches
• Material: chrome vanadium steel
• Finish: corrosion-resistant plated surface
• Design: two open ends per wrench with different metric sizes
• Application area: mechanical and automotive fastening tasks

How to use

Select the wrench end that matches the fastener size and place it fully over the nut or bolt head to ensure even contact. Apply steady force along the wrench handle axis while maintaining control to avoid slipping. For tight spaces, use the opposing open end if clearance improves engagement. Inspect wrench contact surfaces and fastener condition before applying high torque to prevent rounding. After use, wipe clean and store the wrenches in a tray or roll to protect the plating and maintain organization.

Recommendations

Use these double open-ended wrenches for general tightening and loosening where quick end changes and access to both sides of a nut or bolt are required. Avoid using the wrenches as levers for prying or striking with a hammer. For high-torque or precision-critical fasteners, consider using a torque wrench or appropriate socket tool to achieve accurate torque values and reduce wear on fastener heads.
