Wrench STAHLWILLE 17, 13 mm, chrome alloy steel, single piece, 182×26.5×8.4 mm

Wrench STAHLWILLE 17 is an open-ended hand spanner made for 13 mm fasteners, manufactured from chrome alloy steel with a polished chrome finish to resist corrosion. The tool is a single-piece design measuring 182 mm in length, 26.5 mm in width and 8.4 mm in thickness, offering a compact profile suitable for general mechanical work, maintenance and assembly where a reliable 13 mm wrench is required. The spanner incorporates STAHLWILLE's engineered geometry to reinforce areas of highest load while keeping the tool slim and easy to handle.

Advantages

The wrench is drop-forged from high-grade alloy steel and heat treated in continuous furnaces to ensure consistent hardening without scale or decarburisation. Gentle oil quenching and STAHLWILLE's double-T profile provide high bending resistance with reduced weight, resulting in a durable yet manageable tool. A polished, rounded finish reduces local stress concentrations and creates a skin-friendly surface. The forged double hex jaw is designed to be tougher than bolts, and the thinner ring profile and increased nut clearance reduce the risk of jamming in confined spaces. Quality is supported by STAHLWILLE's certified quality assurance processes.

Suitable for

• Assembly and disassembly of mechanical components with 13 mm fasteners
• Routine maintenance and repair tasks in workshops
• Automotive and motorcycle maintenance requiring compact tools
• Field service and equipment servicing where corrosion resistance is needed

Key specifications

• Wrench type: open-ended single-piece spanner for 13 mm nuts and bolts
• Material: chrome alloy steel
• Surface finish: polished chrome for corrosion resistance
• Length: 182 mm
• Width: 26.5 mm
• Thickness: 8.4 mm
• Profile: double-T design for increased stiffness and reduced weight

How to use

Select the wrench side that matches the 13 mm fastener and position the jaw squarely on the nut or bolt head to ensure full contact. Apply steady torque, pulling the wrench toward you rather than using sudden impacts. For tightening, turn clockwise to the required torque; for loosening, turn counterclockwise while maintaining alignment to avoid rounding the fastener. Use the slimmer profile when working in confined spaces to improve accessibility and reduce the chance of jamming.

Usage recommendations

Inspect the wrench before use for signs of wear or deformation. Avoid using the spanner as a hammer or lever extender and do not apply extensions or “cheater” bars that exceed intended leverage. Clean and dry the tool after use and store in a dry toolbox to maintain the chrome finish and prevent corrosion. For safety and best performance, use the wrench only on correctly sized 13 mm fasteners and replace the tool if any cracks or significant wear are detected.
