Set of open-end wrenches Kuźnia Sułkowice 13 pcs 6–32 mm (model 1-131-91-113)

Set of open-end wrenches Kuźnia Sułkowice 13 pcs 6–32 mm (model 1-131-91-113) is a metric flat-wrench kit covering sizes from 6 mm up to 32 mm in single-step increments. The set provides one open-end wrench for each nominal size within the range, designed for general mechanical, automotive and maintenance work where access and rapid turning of hexagonal bolt heads and nuts are required. Each wrench has two opposing open jaws that engage fasteners from the side, enabling use in confined spaces and for quick repositioning without full rotation clearance.

Advantages

The set offers a complete span of commonly used metric sizes in a compact 13-piece assortment, reducing the need to carry multiple individual tools. Wrenches in the set are manufactured to consistent dimensions to ensure reliable fit on standard hex fasteners and to minimize rounding. The open-end design allows access in tight or restricted areas where ring or boxed wrenches cannot be applied. The range from 6 mm to 32 mm covers small machine fastening tasks through larger automotive and maintenance fittings.

Suitable for

• General mechanical and workshop maintenance
• Automotive repair and servicing
• Assembly and disassembly of machinery and equipment
• On-site service work where lightweight, compact tools are required

• Type: open-end (flat) wrench
• Material: forged steel construction suitable for hand-tool applications (manufacturer standard)
• Finish: corrosion-resistant finish for improved durability (manufacturer standard)
• Drive size: metric, nominal sizes in millimetres (mm)

How to use

Select the wrench with the correct nominal size that fits snugly onto the nut or bolt head. Place the open jaws onto the fastener so the load is distributed across the flat faces to reduce the risk of rounding. Apply controlled hand force; for high-torque applications use appropriate tools rated for impact or higher torque rather than an open-end wrench. When working in confined spaces, reposition the wrench after each turn so the open jaw can be reapplied to the next available flat on the fastener.

Usage recommendations

Inspect wrenches before use for wear or deformation and keep them clean and lightly oiled to prevent corrosion. Use the correct size to avoid damaging fasteners; do not use open-end wrenches as hammers or pry bars. For repeated high-torque fastening, consider complementary tools such as torque wrenches or boxed/ring wrenches.
