## Long description

Flat Wrench 10x11 mm Kuźnia Sułkowice model 1-131-13-101 is a two-size open-end hand tool manufactured by Kuźnia Sułkowice, designed for tightening and loosening hexagonal bolts and nuts. The compact design integrates 10 mm and 11 mm jaw openings in a single wrench body, enabling quick switching between common small fastener sizes. The tool is intended for automotive, mechanical and household repair tasks where access and space are limited.
Advantages
The open-end configuration provides immediate engagement with hex fasteners without the need to slip over the end of a threaded rod. A compact, two-size head reduces the number of tools required in a pocket or toolkit, while the solid forged construction ensures durable performance under regular use. The wrench offers accurate jaw fit for reliable torque transfer and reduced risk of rounding fastener corners when used correctly.
Suitable for
 Automotive maintenance and repair involving small nuts and bolts
 Mechanical assembly and disassembly tasks in workshops
 Household repairs and DIY projects requiring compact hand tools
 Situations with limited clearance where a boxed or socket wrench cannot reach
Key specifications
 Wrench type: open-end (flat) wrench with dual jaw sizes
 Jaw sizes: 10 mm and 11 mm
 Material and construction: solid forged steel construction for durability
 Design: compact, double-headed layout for two common metric sizes in one tool
 Finish: corrosion-resistant surface treatment suitable for workshop conditions
 Intended use: hand-operated for tightening and loosening hexagonal fasteners
How to use
Select the jaw size that matches the fastener and slip the open end onto the nut or bolt head. Apply steady hand force in the required direction to tighten or loosen, keeping the wrench aligned with the fastener axis to minimize corner rounding. For higher torque, use short, controlled movements and ensure the wrench fully engages the flats. Do not use the wrench as a hammer or pry bar and avoid applying excessive force beyond hand operation limits to prevent tool or fastener damage.
Usage recommendations
Store the wrench in a clean, dry toolbox to protect the corrosion-resistant finish. Inspect the jaws periodically for wear and replace the tool if excessive rounding or deformation is present. When working on torque-critical fasteners, use a calibrated torque tool as needed and avoid overtightening with an open-end wrench.
