Flat wrench Topex 16 x 17 mm — double-ended open spanner, steel construction

Flat wrench Topex 16 x 17 mm — double-ended open spanner, steel construction is a hand tool designed to turn hexagonal nuts and bolts sized 16 mm and 17 mm. Constructed from steel with a flat profile, this double-ended open spanner enables access in tight spaces and is intended for manual tightening and loosening tasks in repair, assembly, and maintenance environments.

Advantages

The steel construction provides mechanical strength and resistance to wear while the slim, flat profile improves accessibility in confined or shallow recesses. Having two open-end sizes on a single tool reduces the need to switch wrenches during tasks. The simple, solid design offers straightforward handling for common workshop and field operations.

Suitable for

• Automotive repair and maintenance where 16 mm and 17 mm fasteners are used
• Plumbing tasks involving hexagonal fittings in restricted spaces
• Furniture and equipment assembly requiring manual spanners
• General household maintenance and DIY projects

Key specifications

• Type: double-ended open spanner (flat wrench)
• Sizes: 16 mm and 17 mm open ends
• Material: steel construction for strength and durability
• Profile: flat/slim for access in confined spaces
• Drive: manual hand-operated tool, non-ratcheting

How to use

Select the end matching the nut or bolt size, seat the open jaw fully onto the fastener, and apply steady torque by hand in the required direction to tighten or loosen. Ensure the wrench is aligned squarely with the fastener to minimize rounding. For confined areas, use the slim profile to reach the fastener and reposition the wrench as needed to continue turning. Avoid using the tool with added cheater bars or striking it with a hammer.

Usage recommendations

Inspect the wrench before use for visible wear or deformation. Use appropriate personal protective equipment such as gloves and eye protection when working on mechanical systems. Store the spanner in a dry place to reduce surface corrosion and maintain its flat profile for working in narrow spaces.
