Double open end wrench 6, 7mm HEX 4140607

The open-end wrench from SONIC is a high-quality workshop tool made of chrome-vanadium tool steel. These types of wrenches are offered in various nominal sizes and are mainly used for loosening brake lines, as a regular open-end wrench can easily damage connections made of soft materials.

The chrome-vanadium tool steel used in the production of SONIC wrenches is resistant to abrasion and deformation. The chrome layer protects the tools from corrosion and oxidation. The rounded shapes of the transitions between the planes of the solid forged wrench reduce stress at critical points, thereby increasing the tool's durability and making it highly resistant to cracking.
Maintaining narrow dimensional tolerances in the production process and a precisely calibrated socket profile prevent damage to the bolt or nut head and ensure proper force distribution, making it easier to disconnect seized connections.

Thanks to careful craftsmanship, SONIC wrenches are valued for their ergonomic use and high durability.
The reputation of the SONIC brand guarantees that the tools are free from defects and will perform well during daily, intensive use.
