Combination wrench Proline 18 mm, model 35478, length 235.4 mm, 1 piece

The Proline combination wrench 18 mm (model 35478) is a single-piece hand tool with an overall length of 235.4 mm designed for tightening and loosening 18 mm hex fasteners. Forged steel construction with chromium plating and a satin finish provides a balance of strength, corrosion resistance and reduced glare. The open-end and box-end combination design gives access to fasteners in a variety of positions while the box end’s minimum work angle of 5° allows for finer incremental turns in confined spaces.

Advantages

The forged steel body delivers reliable torque transmission and durability for general mechanical work. Chromium plating protects the tool surface against rust and wear, while the satin finish improves grip comfort and reduces reflective glare during use. The combination of open and boxed ends makes the wrench versatile for both quick adjustments and secure, high-torque fastening.

Suitable for

• Automotive repair and maintenance tasks involving 18 mm fasteners
• Workshop assembly and disassembly of machinery and equipment
• Professional mechanic tool sets and service vans
• DIY projects at home requiring a robust 18 mm wrench

How to use

Select the 18 mm Proline combination wrench and place the appropriate end over the hex fastener. Use the open end for quick turning or when space allows, and the box end for a more secure grip and higher torque application. For working in tight spaces, use small-angle movements enabled by the 5° minimum work angle of the box end. Apply steady force along the handle axis to reduce the risk of rounding the fastener and avoid sudden impacts that could damage the tool or fastener.

Usage recommendations

Regularly inspect the wrench for wear or damage, keep the surface clean and lightly oiled to preserve the chromium plating, and store the tool in a dry place. Use the tool within its intended torque limits and avoid using cheater bars or excessive leverage.
