Open-end wrench set Dedra 1408 — 6-piece pack, manual hand tool

Dedra 1408 is a 6-piece open-end wrench set supplied as a single pack. The set contains six fixed-size open-end wrenches designed to grip hexagonal nuts and bolts from two sides. These manual hand tools provide a straightforward mechanical solution for tightening and loosening fasteners where angled or adjustable jaws are not required. The compact set is intended for general mechanical work, automotive maintenance and routine household repairs, offering clearly defined jaw sizes for repeatable engagement of fittings.

Advantages

The open-end wrenches in this Dedra set deliver direct contact with fastener flats, minimizing round-off when the correct size is used. Fixed jaw openings ensure stable torque transfer and simple, reliable operation without moving parts. The six-piece range covers common metric sizes used in general repair tasks, allowing quick selection of the correct tool. Their compact pack format keeps the tools organized and ready for storage in a toolbox or workbench drawer.

Suitable for

• General mechanical assembly and disassembly tasks
• Automotive maintenance and light repair work
• Household plumbing and fixture adjustments
• Furniture assembly and small DIY projects

Key specifications

• Set composition: 6 open-end wrenches with fixed jaw openings
• Function: engage hexagonal nuts and bolt heads on two opposite flats
• Tool type: manual hand tools for turning fasteners without adjustable mechanism
• Typical materials: forged steel construction for strength and wear resistance
• Finish: protective coating to reduce corrosion and surface wear

How to use

Select the wrench with the jaw opening that matches the flat-to-flat measurement of the nut or bolt head. Position the open jaws fully onto the fastener flats, ensure firm seating, and apply controlled turning force in the required direction. For best results, use the wrench on fasteners in good condition and avoid excessive torque that could deform the fastener or the wrench. When accessing confined spaces, align the handle to allow unobstructed rotation while maintaining steady contact with the fastener.

Usage recommendations

Use the correct size from the set to prevent rounding of fastener corners; inspect tools for visible wear or damage before use and store the set in a dry place to limit corrosion. For high-torque applications or damaged fasteners, consider using alternative tools designed for impact or adjustable gripping.
