Wrench (open-end) Kuźnia Sułkowice 14 x 17 mm model 1-131-33-101, forged steel

Open-end wrench Kuźnia Sułkowice 14 x 17 mm model 1-131-33-101 is a dual-head hand tool designed for tightening and loosening hexagonal nuts and bolts. The two open ends provide quick engagement with fasteners of 14 mm and 17 mm across flats, making it suitable for routine maintenance tasks in automotive repair, machinery service, and general workshop work. Forged steel construction delivers mechanical strength and wear resistance while the compact, double-ended layout reduces the need to carry multiple single-size wrenches.

Advantages

The forged steel body provides improved durability and resistance to bending under torque compared with stamped or cast alternatives. Having two common metric sizes on a single tool increases convenience for technicians and hobbyists, saving space in toolkits and pockets. The open-end profile allows access to fasteners in confined areas where socket wrenches cannot reach, and the slim head design aids in use on closely spaced components.

Suitable for

• Automotive maintenance and brake or suspension work
• General machinery and equipment servicing
• Assembly, disassembly and adjustment of household appliances
• On-site repair work and mobile toolkits for service technicians
• Hobbyist and DIY projects requiring metric wrench sizes

Key specifications

• Wrench type: open-end (double-headed)
• Sizes: 14 mm and 17 mm across flats
• Material: forged steel for increased strength
• Finish: matte or protective finish to resist corrosion (manufacturer-applied)
• Overall design: slim heads for access in tight spaces
• Typical applications: hex nuts and bolt fasteners

How to use

Select the end of the wrench that corresponds to the nut or bolt size (14 mm or 17 mm). Position the open jaws fully onto the flats of the fastener to ensure a secure grip and minimize rounding. Apply steady manual force, keeping the wrench aligned with the fastener axis; use short, controlled movements when working in tight spaces. Do not use the wrench with an extension or cheater bar, and avoid striking it with a hammer. Inspect the tool before use for signs of excessive wear or deformation.

Usage recommendations

For consistent performance and safety, store the wrench in a dry toolbox, clean off grease and dirt after use, and periodically check for head distortion or cracks. Use the correct size to reduce fastener damage and wear on the tool. For high-torque applications, consider using an appropriately sized ring or box-end wrench or a torque-controlled tool.
