Open-end wrench STANLEY FMMT13070-0, chromium-vanadium steel, sizes 18×19 mm, length 235 mm

STANLEY FMMT13070-0 open-end wrench is a single-piece hand tool forged from chromium-vanadium steel with a corrosion-resistant satin chrome finish. The wrench features dual open ends in sizes 18 and 19 mm, a length of 235 mm and a weight of approximately 188 g. It is designed for tightening and loosening nuts and bolts in automotive, mechanical and general maintenance work, offering durability and reliable torque transmission in workshop and on-site repair environments.

Advantages

The chrome-vanadium construction provides strength and resistance to wear while the satin chrome finish reduces surface corrosion and eases cleaning. Dual-size open ends (18×19 mm) allow two common sizes in one tool, reducing the number of tools required. The single-piece forged design delivers consistent alignment and improved durability compared with multi-piece constructions. A slight offset on the open ends increases access clearance in confined areas and helps position the wrench on fasteners more easily.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Workshop general maintenance and repairs
• On-site service tasks where a portable hand tool is needed

Key specifications

• Material: chromium-vanadium steel
• Finish: satin chrome (corrosion-resistant)
• Head sizes: 18 mm and 19 mm
• Length: 235 mm
• Weight: approx. 188 g
• Design: single-piece forged open-end wrench with slight offset

How to use

Select the appropriate end (18 or 19 mm) that matches the nut or bolt head. Position the open end fully over the fastener, ensuring full contact on the flat sides to minimize rounding. Apply steady force in the required direction to tighten or loosen the fastener, using the offset to clear obstructions or allow better hand positioning in tight spaces. Maintain control of the tool and avoid sudden, extreme force to prevent slippage or damage to the fastener.

Usage recommendations

For best results, keep the wrench clean and free of oil or debris on the contacting surfaces. Use the correct end size to avoid rounding fastener edges, and store the tool in a dry place to maintain the satin chrome finish. Inspect regularly for wear or damage and replace if deformation or excessive wear is present.
