Teng Tools combination wrench set 10–19 mm, 10 pieces, model 109470104

Teng Tools combination wrench set 10–19 mm, 10 pieces, model 109470104 includes ten metric combination wrenches sized 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19 mm. Each tool features an open-end on one side and a ring-end on the other, providing two engagement options in a single wrench. The set is designed for use in automotive, mechanical and general maintenance tasks where common metric sizes are required.

Advantages

The wrenches provide dual-functionality with open and ring ends to address different access and torque needs without changing tools. Hardened and finished surfaces resist wear during repeated use, and the precise sizing ensures a secure fit on fasteners to reduce rounding. The compact set of ten pieces covers a continuous range of popular metric sizes, making it easier to keep the right tool on hand for routine repairs and adjustments.

How to use

Select the correct wrench size to match the fastener head to avoid damage. Use the open-end when working in tight spaces or where quick placement is needed, and use the ring-end to apply higher torque with more contact area on the fastener. Apply steady, controlled force and ensure the wrench is fully seated on the fastener before applying torque. After use, clean any grime from the wrench and store the set in a toolbox or on a rack to maintain condition and organization.

Usage recommendations

For longer life and consistent performance, avoid using the wrenches as prying tools, and do not apply impact force unless the tool is specified for such use. Regularly inspect the wrench ends for wear and replace tools that show rounding or excessive deformation. When working on precision or safety-critical fastenings, torque should be applied with a calibrated torque wrench where required.
