Hexagon socket bit Wera 05056683001, 3 mm tip, 25 mm length

Wera hexagon socket bit 05056683001 with a 3 mm tip and 25 mm length is a precision accessory for driving hex (Allen) socket screws in electronics, precision assemblies and general maintenance tasks. The bit is designed to fit standard bit holders and ratchets, offering a close fit to screw heads to help reduce cam‑out and fastener wear. Its compact 25 mm overall length makes it convenient for use in confined spaces and for portable toolkits.

Advantages

The Wera 3 mm hexagon socket bit is manufactured to provide accurate engagement with hex socket fasteners, improving torque transfer and reducing rounding of screw heads. Compatibility with common bit holders and ratchets gives flexibility across hand tools and adapters. The short 25 mm profile improves access in tight assemblies while maintaining sufficient length for reliable handling. The bit’s geometry and material selection are intended to increase service life and reduce the need for frequent replacement.

Suitable for

• Precision electronics assembly and repair
• Maintenance of bicycles, small machinery and appliances
• Workshop and on‑site general maintenance tasks
• Use with bit holders, quick‑change adaptors and ratchets

Key specifications

• Tip type: hexagon (Allen) 3 mm
• Overall length: 25 mm
• Compatible drive: standard bit holder and ratchet interfaces
• Typical applications: precision assemblies, electronics, general maintenance

How to use

Insert the 3 mm hexagon bit into a compatible bit holder, quick‑change adapter or ratchet. Ensure the bit is fully seated and securely retained before applying torque. Select an appropriate hand tool to match the required torque for the fastener and turn steadily to avoid slipping. For assembly work in confined areas, the 25 mm length provides access while keeping control of the fastener engagement. Inspect the bit tip periodically for wear and replace if rounding or damage is present.

Usage recommendations

Use the bit with tools that match the required torque and avoid applying excessive force that could damage the fastener or bit. Keep the bit clean and free from debris to maintain accurate fit. For repetitive or high‑torque applications consider using the correct size and a bit designed for impact or heavy‑duty use.
