Set of Double-Ended Open-End Wrenches in Cardboard Box, Unior 11 pcs, sizes 8–32 mm

Unior set of double-ended open-end wrenches in a cardboard box, 11 pieces, covering metric sizes from 8 mm to 32 mm. Each wrench features two different jaw openings, offering a total of 22 fitting sizes in a compact assortment. The set is designed for general fastening and maintenance tasks in automotive repair, workshop environments and household projects where access to nuts and bolts with limited clearance is required.

Advantages

The set provides a broad range of metric sizes in one package, reducing the need to buy individual wrenches. Double-ended design increases versatility while minimizing the number of tools carried. The cardboard box keeps the tools organized and transportable; the compact format simplifies storage. Wrenches are shaped for reliable engagement with fasteners, helping to limit rounding and slippage when correct size selection and proper technique are used.

How to use

Select the wrench jaw that correctly matches the fastener size and position the open end squarely on the nut or bolt to ensure full contact. Apply steady, controlled force in the intended fastening or loosening direction to avoid slipping. For work in confined spaces, choose the shorter or appropriately angled end to obtain necessary access. After use, clean off dirt or grease if present and return the wrench to the cardboard box to keep the set organized and protected from damage.

Usage recommendations

Use the correctly sized wrench for each fastener and avoid excessive impact or hammering on the open ends. For higher torque applications or rounded fasteners, consider using a box-end or socket tool to reduce the risk of damage. Store the set in a dry place to prevent corrosion and inspect tools periodically for wear or deformation before use.
