## Summary description

Open-end wrench Rockforce 25x28 mm (model RF-7542528) made from Cr‑V (chrome‑vanadium) steel.

## Long description

Open-end wrench Rockforce 25x28 mm Cr-V RF-7542528 — Chrome Vanadium is a dual-size fixed open jaw spanner designed for accurate torque transfer on 25 mm and 28 mm hexagonal fasteners. Manufactured from chrome-vanadium steel, this open-end wrench combines a slim profile for access in confined spaces with hardened jaws to resist wear during repeated use. The tool is intended for use in automotive repair, mechanical maintenance and general workshop tasks that require reliable contact with nuts and bolts.
Advantages
This Rockforce open-end wrench offers two common metric sizes in one tool, reducing the need to switch between individual spanners. The chrome-vanadium construction provides improved toughness and fatigue resistance compared with standard carbon steel tools, while the precisely machined jaw openings ensure a stable fit on fasteners to limit rounding. The compact length and slim head profile allow access to fittings in tight assemblies and the finished surface helps protect against corrosion.
Suitable for
 Automotive maintenance and repairs (engine, chassis, brake components)
 Mechanical assembly and disassembly of equipment and machinery
 General workshop and household maintenance tasks
 Situations requiring quick interchange between 25 mm and 28 mm fasteners
Key specifications
 Sizes: 25 mm and 28 mm open jaws
 Material: chrome-vanadium (Cr‑V) steel
 Type: fixed open-end wrench (double-ended)
 Finish: polished/chrome plated surface for corrosion resistance
 Application: manual hand tool for tightening and loosening hexagonal nuts and bolts
How to use
Select the jaw size that matches the flat-to-flat dimension of the fastener and place the open jaws fully onto the nut or bolt head so the wrench makes full contact on both flats. Apply steady force in the intended direction of rotation; avoid sudden impacts or using the wrench with an extension to prevent overstressing the tool. If the fastener is tight, apply controlled pressure and consider using penetrating lubricant to reduce the risk of rounding. After use, wipe clean and store the wrench in a toolbox or rack to maintain the finish.
Usage recommendations
For safe and long-lasting performance, use the wrench only on fasteners that match the marked sizes, avoid using the open-end wrench as a hammer or pry-bar, and do not apply cheater bars or excessive torque beyond manual limits. Periodically inspect the jaw faces for wear and replace the tool if the fit on fasteners becomes loose.
