Combination wrench Proline 35630 — 30 mm, 340 mm length, single piece

Proline 35630 is a single-piece combination wrench with a 30 mm working size and a 340 mm overall length. The tool combines an open-end and a box-end to allow both quick engagement and secure turning of nuts and bolts. Forged construction with chromium plating and a satin finish gives the wrench durability and corrosion resistance while maintaining a practical grip surface. The geometry follows dimension-related requirements of the German DIN 3113 standard and offers higher torque capacity compared with common DIN 899 and ANSI wrenches.

Advantages

The one-piece forged design provides high structural strength and reduced risk of bending or deformation under load. Chromium plating protects the surface from rust and wear, while the satin finish reduces glare and improves handling. The combination of open and boxed ends allows application in tight spaces as well as on fasteners requiring more contact area. Built to meet DIN 3113 dimensional requirements and engineered for up to 60% greater maximum torque compared with standard DIN 899 and ANSI tools, the wrench is suitable for demanding fastening tasks.

Suitable for

• Automotive repair and maintenance where longer leverage is required
• Mechanical assembly and disassembly of machinery and equipment
• Workshop and industrial maintenance tasks on medium to large fasteners
• Field service work where a single robust wrench is preferred

Key specifications

• Working size: 30 mm
• Overall length: 340 mm
• Construction: one-piece forged wrench
• Finish: chromium-plated with satin surface
• Standards: dimensionally compliant with German DIN 3113
• Torque capacity: up to 60% higher maximum torque than comparable DIN 899 and ANSI wrenches

How to use

Select the 30 mm opening to match the fastener, position the open-end for quick turning or fit the box-end over the nut for full contact and reduced rounding. Apply steady, controlled force and avoid sudden impacts; the longer 340 mm length provides increased leverage for loosening tight or rusted fasteners. When working in confined areas, use the appropriate end to gain access while maintaining secure engagement with the fastener.

Usage recommendations

Inspect the wrench for visible damage before use, keep contact surfaces clean and free of oil for safer handling, and avoid using the wrench with additional pipes or cheater bars that exceed the intended leverage to prevent tool or fastener damage. Store in a dry place to preserve the chromium finish.
