## Summary description

Proline C-type open-ended wrench 16x17 mm (MPN 5364364, EAN 5903755364364) is a hand tool designed for turning hex nuts and bolts of 16 mm and 17 mm sizes. The compact C-shaped head provides access in confined spaces and the dual-size design reduces the number of tools needed. Suitable for automotive maintenance, plumbing, assembly and general repair tasks.

## Long description

Proline open-ended C-type wrench 16x17 mm is a compact hand tool intended for turning hex nuts and bolts with 16 mm and 17 mm flats. The C-shaped head gives improved access in confined or partially obstructed spaces where conventional wrenches struggle. Dual-size jaws reduce the need to change tools during a job and the single-piece construction provides a simple, reliable design for workshop, garage, or on-site use.
Advantages
The C-type open-ended design allows access to fasteners located in tight recesses and along edges. Two adjacent sizes in one wrench (16 mm and 17 mm) save space in a toolbox and speed up work by reducing tool changes. A compact profile makes the tool suitable for use in cramped installations and helps reach nuts without removing nearby components. The open-ended jaws permit quick placement on nuts and bolts and facilitate turning where a ring or socket cannot fit.
Suitable for
Automotive maintenance and light repairs
Plumbing installations and pipe fittings
Assembly of furniture and equipment
General household and workshop repair tasks
Key specifications
Wrench type: open-ended, C-type head
Sizes: 16 mm and 17 mm
Material: forged steel (single-piece construction)
Finish: corrosion-resistant surface treatment
Profile: compact, low-profile head for limited-access use
How to use
Select the side of the wrench that matches the nut or bolt size and fit the open jaws fully onto the flats of the fastener to ensure secure engagement. Apply steady turning force in the required direction; for high-torque loosening, ensure the wrench is seated squarely to minimize rounding of fastener corners. The slim C-shaped head enables access to fasteners in narrow gaps—position the wrench carefully and use controlled force to avoid slipping. After use, store in a toolbox or on a hanging rack to prevent damage to the jaws.
Usage recommendations
Use the wrench for matching 16 mm and 17 mm hex fasteners only. Avoid using cheater bars or excessive impact force on the open-ended jaws to prevent deformation. For fasteners requiring higher torque or where full circumferential contact is needed, consider using a ring or socket wrench. Keep the tool clean and periodically inspect the jaws for wear or rounding to maintain safe operation.
