Flat wrenches Dedra DED1403 set 8 pcs, sizes 8–22 mm, chrome vanadium

Set of 8 flat wrenches Dedra DED1403 provides a selection of common metric sizes from 8 mm to 22 mm in a compact, flat design. Manufactured from chrome vanadium (CrV) steel, each wrench is intended for general fastening tasks where access is limited by low-profile heads or tight clearances. The set covers the most frequently used nut and bolt sizes for automotive maintenance, household repairs and workshop projects.

Advantages

The chrome vanadium construction delivers strength and wear resistance for repeated use. The flat profile allows the wrenches to fit into narrow spaces and against flat surfaces where bulkier tools cannot reach. Sizes are graduated across the set to provide a solution for a wide range of metric fasteners without the need to carry multiple individual wrenches. The simple, single-piece design reduces points of failure and eases cleaning and storage.

Suitable for

• Automotive repairs and routine vehicle maintenance
• Household plumbing and furniture assembly
• General workshop use and mechanical servicing
• Tight or low-clearance fastening applications

Key specifications

How to use

Select the wrench that matches the nut or bolt size, position the flat head squarely on the fastener, and apply steady force to tighten or loosen. For confined spaces, orient the thin edge of the wrench to clear adjacent surfaces, and use short, controlled movements to avoid slipping. After use, wipe the tools clean and store them in a toolbox or rack to prevent corrosion and maintain the working edges.

Usage recommendations

Use the appropriate size to avoid rounding fastener corners, and avoid applying excessive torque beyond the wrench capacity. For high-torque jobs, consider using a torque wrench or a socket set. Keep the tools dry and lubricated if needed to prolong service life.
