Screwdriver bits set Dedra 18A04H50-03, 3 pcs, 25 mm, hex (metric)

Dedra 18A04H50-03 is a compact set of three screwdriver bits with 25 mm length and metric hex (Allen) tips, designed for use with manual or powered bit holders and ratchets. The bits deliver straightforward interchangeability for assembly, maintenance and repair tasks where metric hex fasteners are used. The compact length and standard shank profile allow use in confined spaces and on machines or handles that accept standard driver bits.

Advantages

The set combines three commonly used metric hex sizes in a compact, easy-to-store format, enabling quick bit changes during repetitive fastening work. All bits are suitable for both manual and powered drivers, offering consistent engagement with hex fasteners to reduce slippage and rounding. The 25 mm length strikes a balance between reach and control, improving access in tight assemblies while maintaining torsional strength for routine fastening.

Suitable for

• Furniture assembly and disassembly
• Electronics enclosures and internal fastening
• Automotive trim and small mechanical repairs
• General mechanical fastening with metric hex fasteners

Key specifications

• Tip type: metric hex (Allen)
• Set size: 3 pieces
• Bit length: 25 mm
• Intended drive interface: standard bit shank for manual or powered holders
• Typical applications: assembly, maintenance and repair fastening tasks

How to use

Select the bit that matches the head size of the metric hex fastener, insert the bit into a compatible bit holder, ratchet or powered driver, and ensure a secure fit before applying torque. Use steady, even pressure when driving or removing fasteners to minimize slipping or rounding of the fastener head. For confined spaces, the 25 mm length provides modest reach while allowing comfortable control for manual operation.

Usage recommendations

Inspect bits periodically for wear or damage and replace any bit that shows rounding or chipping at the tip. When using powered drivers, set torque to an appropriate level for the fastener and material to avoid over-tightening. Store the bits in a dedicated pouch or holder to protect the tips and keep sizes organized.
