Wrench set MODECO flat open-end 17 x 19 mm MN-50-440

MODECO flat open-end wrench MN-50-440 combines two common jaw sizes, 17 mm and 19 mm, in a single compact hand tool. Designed for direct torque application to hexagonal nuts and bolts, this wrench is intended for use in workshops, service vans and home toolkits where access is limited and a slim profile is required.

Advantages

The flat open-end design delivers a low-profile fit that reaches into narrow spaces and on shallow fasteners. Having both 17 mm and 19 mm jaws on one tool reduces the number of separate wrenches needed and speeds up simple tightening and loosening tasks. The solid construction provides stable contact with fastener flats to minimise rounding and allow controlled torque transfer.

Suitable for

• Tightening and loosening 17 mm and 19 mm hex nuts and bolts
• Automotive maintenance and light mechanical repairs
• Plumbing assembly and fastening in confined spaces
• General workshop and household repair jobs

Key specifications

• Open-end jaw sizes: 17 mm and 19 mm
• Flat, low-profile head for narrow access
• Hand tool intended for manual torque application
• Compact, two-size combination format
• Suitable for use on standard hexagonal fasteners

How to use

Select the jaw size that matches the nut or bolt head and position the open-end around the flat faces of the fastener. Apply steady, controlled force in the required direction to tighten or loosen; avoid sudden impacts or excessive bending loads. Keep the wrench aligned with the fastener to reduce slippage and wear on the tool and the fastener.

Usage recommendations

Inspect the wrench for visible damage or wear before use. For higher torque requirements use a properly sized boxed or torque-rated tool rather than an open-end wrench. Store the tool in a dry place to prevent corrosion and maintain clean contact surfaces for reliable engagement.
