The SONIC combination wrench is a high-quality workshop tool made of chrome-vanadium tool steel. SONIC wrenches are offered in various nominal sizes ranging from 7 to 32 mm.

The alloy steel used by SONIC is resistant to abrasion and deformation, and the tool is protected against corrosion and oxidation. The rounded shapes of the transition between the planes of the solid forging help reduce stress at critical points, making these wrenches durable and 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 loosen 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.
