Wrench (combination) PARTNER 16 mm, length 200 mm, Cr-V steel

Combination wrench PARTNER 16 mm is a medium-length hand tool with a total length of 200 mm, designed for turning 16 mm hex fasteners. Constructed from chromium-vanadium (Cr-V) steel, this wrench combines an open-end jaw on one side and a boxed/ring end on the other to provide two common engagement methods for nuts and bolts. Its compact 200 mm length offers a balance between access in confined spaces and leverage for general mechanical, maintenance and assembly tasks.

Advantages

The Cr-V steel construction delivers enhanced strength and wear resistance compared with plain carbon steel, helping the wrench retain its shape under typical torque loads. The combination of an open-end and a ring end increases versatility: the open end allows quick placement on fasteners in tight or angled positions, while the ring end provides full-circumference contact for more secure torque transfer. The 200 mm length offers improved reach over short wrenches while remaining manageable for hand use.

Suitable for

• General mechanical repairs and maintenance
• Assembly of machinery and equipment where 16 mm fasteners are used
• Automotive and bicycle maintenance requiring medium-length wrenches
• Household repair tasks and DIY projects with 16 mm nuts and bolts

Key specifications

• Nominal size: 16 mm
• Overall length: 200 mm
• Material: chromium-vanadium (Cr-V) steel
• Configuration: combination wrench with open-end and ring/box end
• Ends: angled open jaw and full-contact ring end for secure grip

How to use

Select the wrench so the 16 mm opening matches the fastener. Use the open end for quick placement or when working in limited clearance, positioning the jaws fully around the fastener where possible to minimize slippage. Use the ring end when higher torque or a more secure engagement is required; align the ring over the fastener head or nut and apply steady force in the intended direction of rotation. Maintain controlled, even pressure to avoid rounding fastener corners and inspect the tool for wear before use.

Usage recommendations

For safe and effective use, keep the wrench clean and free of oil or grease on the gripping surfaces. Avoid using cheater bars or excessive impact force; if higher torque is needed, use an appropriately sized torque tool or socket. Store the wrench in a dry place to reduce corrosion and periodically check for deformation or cracking in the working ends.
