Combination wrench Proxxon 17 mm PR23917, chrome-plated steel, open and box ends

Proxxon 17 mm combination wrench PR23917 is a hand tool designed for tightening and loosening 17 mm fasteners. It combines an open-end jaw for quick engagement and a boxed end for secure torque application. Manufactured from chrome-plated steel, the wrench offers corrosion resistance and a durable working surface suitable for mechanical, automotive and household repair tasks where a compact, single-size wrench is required.

Advantages

The chrome-plated steel construction provides protection against rust and wear while ensuring a smooth finish that is easy to clean. The combination of an open and boxed end makes the tool versatile: the open end allows rapid positioning on bolts and nuts in confined spaces, while the boxed end delivers better contact and torque distribution to reduce rounding of fasteners. The single-piece design improves strength and reliability during repeated use.

Suitable for

• Automotive maintenance and repair on 17 mm fasteners
• Mechanical assembly and servicing where a reliable 17 mm wrench is needed
• Household repairs and DIY projects involving 17 mm nuts and bolts
• Tightening and loosening tasks in workshops and garages

Key specifications

• Size: 17 mm working profile
• Design: combination wrench with open and boxed ends
• Material: chrome-plated steel for corrosion resistance
• Finish: polished chrome surface
• Construction: single-piece forged style for strength

How to use

Select the 17 mm wrench and position the appropriate end on the fastener. Use the open end for quick placement or when access is limited; use the boxed end for higher torque and better contact to avoid rounding. Apply steady force with controlled wrist movement, taking care not to exceed the tool's capability. Inspect the wrench before use for damage or excessive wear and keep the contact surfaces clean for optimal grip.

Usage recommendations

Use the boxed end when higher torque is required and switch to the open end for speed or awkward angles. Store the wrench in a dry place to maintain the chrome finish and periodically clean and lightly oil the tool to prolong service life.
