Open-end wrench Kuźnia Sułkowice 27 x 30 mm model 1-131-60-101

Open-end wrench Kuźnia Sułkowice 27 x 30 mm model 1-131-60-101 is a dual-head manual spanner designed for working with hexagonal nuts and bolts in two adjacent metric sizes. The tool features fixed 27 mm and 30 mm open jaws arranged on a single-piece body to provide leverage and consistent torque transfer. Intended for use in mechanical, automotive and general workshop environments, the wrench offers a straightforward solution when two common sizes are required in a compact format.

Advantages

The single-piece construction enhances strength and reduces the risk of failure under torque compared with multi-component designs. Fixed open jaws provide rapid access to fasteners without the need to reposition or adjust the tool. The dual-size configuration saves space in a tool kit by combining two commonly used sizes into one tool and allows quick switching between 27 mm and 30 mm fasteners. The robust build supports repeatable torque application and routine workshop use.

Suitable for

• Automotive repair and maintenance involving 27 mm and 30 mm hex fasteners
• Mechanical assembly and disassembly tasks on equipment and machinery
• General workshop and garage use for tightening and loosening bolts
• Situations where a compact, dual-size manual wrench is preferred

Key specifications

• Open jaw sizes: 27 mm and 30 mm
• Tool type: open-end wrench (dual-head)
• Design: single-piece construction for improved strength
• Intended use: manual tightening and loosening of hexagonal nuts and bolts
• Application areas: automotive, mechanical, workshop environments

How to use

Select the jaw corresponding to the fastener size (27 mm or 30 mm) and position the open end fully over the nut or bolt head. Apply steady force to the handle in the required direction to tighten or loosen the fastener, keeping the wrench seated squarely on the flats to minimize rounding. For stubborn or corroded fasteners, apply penetrating lubricant and allow time to work before reattempting. Use controlled force and avoid impact blows; the tool is designed for manual torque application.

Usage recommendations

Inspect the wrench before use for visible damage or wear at the jaws. Match the correct jaw size to the fastener to reduce slip. Store the wrench in a dry place and clean metal surfaces after use to prevent corrosion. For tasks requiring high torque, use appropriate safety practices and consider using a tool specifically rated for higher torque to avoid exceeding the wrench's capacity.
