Combination wrench Proline 25 mm, model 35625, length 290 mm, 1 piece

Proline combination wrench 25 mm, model 35625, length 290 mm, single piece is a forged hand tool that combines an open-end and a boxed end to engage 25 mm nuts and bolts. The tool is chromium-plated with a satin finish and designed to meet the dimension-related requirements of German DIN 3113 standard. With a 290 mm length it provides leverage for tightening and loosening fasteners while maintaining a precise fit on mating surfaces.

Advantages

The wrench is forged for strength and durability and has a chromium-plated satin surface to resist corrosion and reduce glare during use. The closed (box) end offers full contact over the fastener head for secure torque transmission, while the open end allows access in confined or offset positions. The design complies with DIN 3113 dimensions and delivers up to 60% higher maximum torque compared with tools produced to German DIN 899 and US ANSI dimensional standards, resulting in improved load capacity under heavy fastening tasks.

Suitable for

• Automotive repair and maintenance tasks requiring a 25 mm spanner
• Mechanical assembly and disassembly of machinery with 25 mm fasteners
• Industrial and workshop maintenance where precise fit and higher torque are needed
• Plumbing or construction jobs where access alternates between open and boxed engagement

Key specifications

• Size: 25 mm across flats
• Length: 290 mm
• Construction: forged steel
• Finish: chromium-plated, satin
• Ends: combination (open-end and box-end)
• Standards: dimension-related compliance with DIN 3113
• Performance: up to 60% higher maximum torque versus DIN 899 / ANSI equivalents

How to use

Select the 25 mm combination wrench for the corresponding nut or bolt head. Place the box end onto the fastener for maximum contact and torque when space allows; use the open end where clearance requires angled or side access. Apply steady force, keeping the wrench aligned with the fastener to reduce rounding. For loosening, position the wrench to turn in the appropriate direction and use controlled leverage; for tightening, avoid overtightening by applying gradual force and checking torque where required.

Usage recommendations

Inspect the wrench before use for signs of wear or damage. Use appropriate personal protective equipment and avoid using the wrench as a hammer or cheater bar. Store in a dry place to preserve the chromium finish and maintain tool performance.
