Hex screwdriver bits Dedra H4 x 25 mm, set of 3, blister pack

Set of three Dedra hex screwdriver bits H4 x 25 mm supplied in a blister pack. These H4 (4 mm) hex bits provide a standard 25 mm shaft length and are compatible with manual and powered screwdrivers that accept replaceable bits. They are intended for tasks involving hex-head fasteners where a medium-short bit length offers control and access in shallow recesses.

Advantages

The set includes three identical H4 bits, offering quick replacement and reduced downtime during assembly or repair. Standard 25 mm length balances reach and stability, making the bits suitable for use in tight or shallow workspaces. Manufactured to meet typical tool industry dimensions, the bits fit common bit holders and drivers and can be used with manual handles or powered drivers when a hex H4 tip is required.

Suitable for

• Assembly and disassembly of furniture and fixtures with 4 mm hex fasteners
• Maintenance and repair of equipment using hex-head screws
• General household tasks requiring H4 hex bits
• Workshop and professional applications where spare bits are needed

Key specifications

• Bit type: Hex (H4 / 4 mm)
• Shaft length: 25 mm standard length
• Quantity: 3 pieces per blister pack
• Compatibility: Designed for bit holders and drivers that accept replaceable bits

How to use

Select an H4 bit from the blister pack and insert it into a compatible bit holder or driver until it is securely seated. For manual work, fit the bit into a suitable screwdriver handle; for powered use, install it in a compatible chuck or quick-change holder. Apply steady, controlled torque to engage the fastener head, avoiding excessive force to prevent cam-out or damage to the bit or fastener. After use, return unused bits to the blister pack to protect the tips and keep them organized.

Usage recommendations

Use appropriate torque settings when operating with powered drivers and inspect bits regularly for wear or rounding. Replace bits that show visible damage to maintain proper fit and prevent damage to fasteners. Store the blister pack in a dry place to avoid corrosion.
