Open End Wrench HAZET 450N/12

The HAZET 450N/12 open end wrench is a double-ended hand tool manufactured from chromium-vanadium steel with a chrome finish. It combines two common size pairs, 6x7 mm and 27x32 mm, in a single forged body designed for repeated use. The tool's construction emphasizes durability, corrosion resistance and mechanical strength while keeping the overall weight and balance suitable for handheld operations.

Advantages

The chromium-vanadium steel construction provides high tensile strength and wear resistance for long service life. A chrome-plated surface improves corrosion protection and simplifies cleaning after work. The double-ended design reduces the number of tools needed for jobs that require multiple metric sizes, while the forged single-piece body increases reliability under torque. Size markings are clearly visible to help quick identification during work.

Suitable for

• Tightening and loosening metric hex nuts and bolts in maintenance and repair tasks
• Automotive and motorcycle maintenance where compact, durable wrenches are required
• Workshop and professional trades requiring a robust open end wrench
• Home DIY projects and general household repairs

Key specifications

• Material: Chromium-vanadium steel (Cr-V)
• Finish: Chrome-plated surface for corrosion resistance
• Sizes: 6 x 7 mm and 27 x 32 mm (double-ended)
• Weight: Approximately 1.94 kg
• Design: Forged single-piece construction, open-end heads on both ends

How to use

Select the appropriate open-end size for the nut or bolt and place the wrench over the fastener so that the flats of the jaw fully engage the nut faces. Apply steady pressure in the required direction, taking care to maintain alignment to avoid rounding the fastener. For higher torque requirements, ensure correct body positioning and use controlled force; do not use the tool as a hammer or extend the handle with additional leverage. After use, wipe the tool clean and store it in a dry location to maintain the chrome finish.

Usage recommendations

Use the wrench only on the specified metric sizes to prevent damage. Inspect the open ends periodically for wear and deformation, and replace the tool if jaws show significant rounding. Keep the chrome finish clean and lightly oiled if stored for long periods in humid environments.
