Screwdriver bit set Dedra 18A54H50-02, 2 pcs, 25 mm, metric hex tips

Dedra 18A54H50-02 is a two-piece screwdriver bit set with metric hex (Allen) tips, each bit measuring 25 mm in length. These compact hex bits are intended for use with bit holders, compact impact drivers, or hand ratchets and are suitable for fastening and maintenance tasks on furniture, machinery and electronic assemblies where short, precise reach is required.

Advantages

The set contains two identical 25 mm metric hex bits made from hardened tool steel for reliable torque transfer and wear resistance. Their short length provides improved control in confined spaces and reduces leverage for safer, low-profile fastening. The uniform geometry of the hex tips ensures consistent engagement with fasteners, reducing the risk of rounding or slippage during installation or removal.

Suitable for

• Assembly and disassembly of furniture with metric hex fasteners
• Maintenance of machinery and equipment with limited access points
• Electronics and small appliance repair where compact driver bits are needed
• Use with bit holders, compact impact drivers, and hand ratchets

Key specifications

• Number of pieces: 2
• Tip type: Metric hex (Allen)
• Tip length: 25 mm
• Compatibility: Standard 1/4" hex bit holder interfaces
• Material: Hardened tool steel (heat-treated for durability)

How to use

Select the correct metric hex size for the fastener to ensure secure engagement. Insert the 25 mm bit into a compatible 1/4" hex bit holder, compact impact driver, or hand ratchet. Apply steady axial pressure while turning to avoid cam-out; for delicate assemblies, use controlled torque settings. Inspect the tip before use for wear or damage and replace bits that show deformation or rounding to protect fasteners and ensure reliable performance.

Usage recommendations

Use the bits for short-reach tasks and confined spaces where full-length bits would be impractical. For high-torque applications, verify compatibility with your driver and consider using longer or specialized bits rated for impact use if required. Keep bits clean and store them in a dedicated holder to maintain tip geometry and extend service life.
