Combination wrench Proline 35641 41 mm, 550 mm length, single piece

Proline 35641 is a single-piece combination wrench with a 41 mm jaw and a total length of 550 mm designed for fastening and loosening nuts and bolts. The tool integrates an open-end profile on one side and a ring-end profile on the other, offering two contact methods in a single tool. Manufactured from forged steel with a satin chromium-plated finish, this combination wrench is produced to meet the dimensional requirements of German DIN 3113 and is engineered to provide greater torque capacity compared with common DIN 899 and US ANSI designs.

Advantages

The one-piece forged construction ensures high structural strength and improved load distribution during use, while the satin chromium plating provides corrosion resistance and reduces glare in work environments. The combination of an open jaw and a boxed ring end allows quick initial engagement with the open end and secure final torque application with the ring end. The long 550 mm length increases leverage for larger fasteners and the tool’s geometry conforms to DIN 3113 dimensions, ensuring compatibility with standardized fasteners.

Suitable for

• Automotive repair and heavy vehicle maintenance
• Industrial assembly and machinery servicing
• Construction and structural bolting tasks
• Maintenance workshops and plant maintenance

Key specifications

• Jaw size: 41 mm
• Overall length: 550 mm
• Construction: single-piece forged design
• Finish: satin chromium-plated
• Standards: dimensionally produced to German DIN 3113
• Torque capacity: up to 60% higher maximum torque compared with typical DIN 899 and ANSI wrenches

How to use

Select the 41 mm combination wrench for the appropriate nut or bolt head and position the open end to engage quickly for alignment or initial turning. For final tightening or loosening under load, use the ring end to fully enclose the fastener head and apply steady force. Use the full length of the 550 mm handle to gain mechanical advantage when higher torque is required. Inspect the tool before use for signs of wear or damage and ensure correct seating on the fastener to avoid rounding.

Usage recommendations

To preserve performance and safety, avoid applying impact or hammer force to this hand wrench; use appropriate torque techniques and, where specified, a calibrated torque wrench for precise tightening. Store the tool in a dry environment to maintain the satin chromium finish and periodically clean and lightly lubricate contact surfaces to prevent corrosion.
