Pipe wrench / double-ended spanner Topex 16 x 17 mm model 35D935

Topex double-ended spanner 16 x 17 mm model 35D935 is a compact hand tool designed for tightening and loosening hexagonal nuts and bolts of 16 mm and 17 mm sizes. The two-size open-end design allows immediate switching between the two common metric sizes without changing tools, making it suitable for a range of repair and maintenance tasks in automotive, plumbing and household applications. The spanner is built for frequent use and provides a reliable contact surface on fasteners.

Advantages

The double-ended construction combines two wrench sizes in a single, space-saving tool, reducing the number of tools needed in a kit. Each open jaw is shaped to fit metric hex heads precisely, improving torque transfer and minimizing slippage. The compact length and solid metal manufacturing deliver durability and easier access in confined spaces compared with longer wrenches. The spanner’s simple design supports repeated use and straightforward cleaning.

Suitable for

• Tightening and loosening 16 mm and 17 mm hex nuts and bolts
• Automotive maintenance and light vehicle repairs
• Plumbing connections and fixtures with metric fasteners
• Household maintenance and assembly of furniture or equipment

Key specifications

• Open-end sizes: 16 mm and 17 mm
• Double-ended, two-size spanner configuration
• Hand tool for manual torque application
• Compact length for working in limited spaces
• Durable metal construction suitable for repeated use

How to use

Select the jaw corresponding to the fastener size and place the open end fully over the nut or bolt head to ensure proper seating. Apply steady, controlled force to turn the spanner in the required direction; use slow, deliberate movements to reduce the risk of rounding the fastener. When access or leverage is limited, position the tool so the force is applied along the plane of the fastener. After use, wipe the tool clean and store in a tool roll or toolbox to protect the working surfaces.

Usage recommendations

Use the 16 mm end for 16 mm fasteners and the 17 mm end for 17 mm fasteners; avoid using either end on damaged or heavily rounded heads. Do not use the spanner as a hammer or pry bar. For high torque requirements, consider using a longer-handled wrench or a properly sized socket and ratchet to reduce the risk of tool or fastener damage.
