Combination wrench 14 mm JOBIprofi model W16314, 14mm open and box ends

JOBIprofi combination wrench W16314 is a 14 mm hand tool that combines an open-end and a 12-point box-end on a single piece. It is designed for tightening and loosening 14 mm nuts and bolts for automotive, mechanical and household repairs. The fixed-size design delivers direct torque transfer and stable engagement with fasteners, while the slim profile improves access in confined or recessed areas.

Advantages

The 14 mm JOBIprofi combination wrench offers a durable construction suited to regular mechanical work. The open-end allows rapid placement and adjustment on hex heads, while the box-end provides more contact area for secure torque application and reduced risk of rounding. The one-piece design minimizes play between ends and helps maintain alignment under load, and the compact length improves reach in tight spaces.

Suitable for

• Automotive maintenance and repairs involving 14 mm fasteners
• Mechanical assembly and disassembly tasks on engines and machinery
• Home and workshop repairs requiring a reliable 14 mm wrench
• Working in confined spaces where a slim-profile wrench is preferred

Key specifications

• Size: 14 mm fixed opening and box-end
• Ends: open-end and 12-point box-end on the same tool
• Material: hardened tool steel (manufacturing material typical for this type of wrench)
• Finish: corrosion-resistant surface treatment for extended service life
• Profile: slim head and shank profile for improved access

How to use

Position the open-end or box-end of the JOBIprofi 14 mm combination wrench on the corresponding 14 mm nut or bolt head. For initial loosening or quick adjustments, use the open-end; for final tightening or applying higher torque, use the box-end to achieve more contact and reduce slippage. Apply steady, controlled force and avoid sudden impacts. When working in confined areas, orient the slim head to gain clearance and, where possible, use multiple engagement positions on the box-end to incrementally rotate fasteners.

Usage recommendations

Inspect the wrench before use for signs of wear or rounding. Do not use the tool with extension bars or cheater pipes, and avoid striking with a hammer. Store in a dry place and clean after use; apply light lubrication to prevent corrosion if the tool is not frequently used.
