Socket Bit 1/4" 4 mm, NEO tools 08-220, 6-point (hexagon)

1/4" drive 4 mm socket bit from NEO tools (model 08-220) with a 6-point (hexagon) profile. Designed for use with 1/4" bit holders, ratchets and compact driver tools, it provides a precise fit for hex fasteners and enables controlled torque transfer in assembly, repair and maintenance tasks in electronics, automotive and household applications.

Advantages

The 6-point (hexagon) profile ensures uniform contact with fastener flats, reducing the risk of rounding and improving torque transmission. The 1/4" drive format is compatible with a wide range of bit holders and compact ratchets, offering versatility for confined spaces. The 4 mm size is well suited for small to medium hex fasteners commonly found in electronics and precision mechanical assemblies. Manufactured to typical professional standards, the bit balances durability with accurate fit to support repeated use.

Suitable for

• Assembly and disassembly of small hex fasteners in electronics
• Light automotive and motorcycle maintenance tasks
• Household repairs and furniture assembly requiring 4 mm hex bits
• Use with 1/4" bit holders, low-profile ratchets and compact drivers

Key specifications

• Drive size: 1/4"
• Bit profile: 6-point (hexagon)
• Hex size: 4 mm
• Compatibility: standard 1/4" bit holders and ratchets
• Typical use: assembly, repair and maintenance tasks

How to use

Insert the 1/4" drive end of the socket bit into a compatible bit holder or ratchet until it seats securely. Place the hex end onto the fastener head, ensuring full contact between all six flats before applying torque. Apply steady, controlled force and avoid excessive impact or prying motions that could damage the fastener or the bit. After use, store the bit in a protective case or holder to prevent corrosion and preserve the hex profile.

Usage recommendations

For optimal performance, match the 4 mm hex bit to fasteners of the same nominal size, use appropriate torque settings for the application, and avoid using the bit in high-torque impact tools unless specifically rated for such use.
