Combination wrench 16 mm NEO tools 09-416, open and box ends, chrome-plated steel

NEO tools combination wrench 16 mm (model 09-416) is a hand tool designed for tightening and loosening hexagonal nuts and bolts. The tool features an open jaw on one end and a box (ring) end on the other, offering two engagement options in a single piece. The chrome-plated steel construction provides corrosion resistance and facilitates cleaning after use, making it suitable for varied working environments from workshops to maintenance sites.

Advantages

The dual-ended design combines accessibility of an open jaw with the secure grip of a box end, enabling efficient work on both exposed and recessed fasteners. Chrome plating improves resistance to rust and simplifies surface cleaning while maintaining the underlying steel strength. The 16 mm size corresponds to common metric fasteners used in automotive, industrial and household applications, allowing straightforward replacement or tightening without adapters.

Suitable for

• Automotive repairs and part replacement involving 16 mm fasteners
• General maintenance and service tasks in workshops and facilities
• Assembly and disassembly of machinery and equipment with metric bolts
• Domestic DIY tasks requiring a reliable 16 mm wrench

Key specifications

• Type: combination wrench with open and box (ring) ends
• Size: 16 mm across flats
• Material: chrome-plated steel
• Finish: polished chrome plating for corrosion resistance and easy cleaning
• Ends: one open jaw and one 12-point/box end for firm engagement

How to use

Select the 16 mm end that matches the nut or bolt head. Use the open jaw end where quick placement or access to confined sides is required; use the box end for a more secure grip and to reduce risk of rounding fasteners. Position the wrench squarely on the fastener flats, apply steady force in the required direction, and avoid sudden impacts. For higher torque needs, ensure the wrench is fully seated on the fastener and use controlled force rather than extensions that may overload the tool.

Usage recommendations

Inspect the wrench for wear or damage before use, keep the chrome-plated surface clean and lightly oiled to maintain corrosion resistance, and store in a dry toolbox. Use the correct 16 mm size to prevent rounding fasteners; do not use the wrench as a hammer or pry bar.
